Ionization Energy and Atomic Radius

[AzureSkyButterflies]

very simply, metals lose their electrons to become positively charged cations. while on the other hand, non-metals gain electrons to become more negatively charges anions

[truelyrandom]

this is so helpful thank you

[doodle101bf]

This helped me ACE my final, i got my 3.8 GPA!!!!!!! you are a great teacher. Keep it up :)

[janaegazagurl101]

OMG it took this guy 9 mins to teach this to me and its been over a week && i still cnt learn this from my teacher THANK YOU SOOO MUCH

[mkpsurf05]

I cannot express my gratitude for this video! It was so helpful I wish you were my chemistry professor. That is the most accurate explanation and analogy I have ever had! Thanks again!

[ItsaStringThing]

oh my gosh, that was the best chemistry lesson I have ever had. where do you get all the energy to add the hand motions and fun analogies. I have to say though, I got a bit confused by the two different anologies you had at work. The old lady/thug analogy suggests that bigger atoms (thugs) will be hard to steal from. However, the dangling purse analogy tells us that bigger atoms (danglers) are easier to steal from. I would maybe just use the second anology if it were me.

[AcousticChamp]

I figure its an all around bad situation if the tough guy is carrying a purse.

[finestchineseboy]

what do i do if my chem teacher makes me fall asleep??

[kielymawiee]

bless you oh my god

so helpful, thank you so much!

[belenysanti]

i cannot pay attention, as he talks i just keep imagining he is a grown up justin bieber

[divinequeenheaven1]

This was very helpful thank you very much!

[JustAskRose]

Thank you so much for your help! Im going to do so well on my test tomorrow! I was so interested 2! You have a great speaking voice.

[katiiee292]

come to my school?

[mscut3yy]

thank you so much , this is so helpful. I wish you are my chem teacher!

[Amanixox]

thanks :) this was really helpful

[azndanyo]

i wish this guy was my chem teacher..

[alexespino101]

thankyou!:D I finally understood this right before the day of the exams :D

[MrsRudilove1]

Man I LOVVVVVE U! <3

[krissayybooboo1]

WOW this helped so much! Thank you! :D

[andrew789987]

@tdewitt451 you are the best f-ing teacher ever. its so easy to understand what you are saying and the analogies are so helpful. I dont even know who the f*** would dislike ur videos. You are going to help me ace my test tomorrow, thank you.

[avengedTheShadows]

i like this. alot

[hystericalmarge]

this is a really good (and lazy) way to learn! thank you

[Sano22n]

old lady atoms, gangsta thug atoms LOL

[ctravih]

whoa whoa whoa, this is illogiacal. i.e. Men dont wear purses

[jessicagarciardz]

OMG I LOVE YOU!!!! THANKS THANKS THANKS THANKSSS !!! U SAVED ME

[Viewtifulboi]

Thank you so much! You just saved me a bunch of time!

[sadhana96]

You are the best teacher ever..thks

[pwnuloser3200]

Gansta thug atoms

[justc94]

he's my teacher! :) this explanation makes it so easy to understandd! I had sooo many "ah ha" moments watching this...

[snowpants123]

WOW the story defintlyyyyyy made me understand better ..and i dont agree with the guy who said use more techinical stuff...because i could just get tht off of google. i need someone to explain it to me slow and simply

[pwnuloser3200]

Holy crap ur good

[MegaGeekie1]

Great analogy - great ability to communicate the theory in a fashion most would embrace ( no pun intended ;) 

[mrsbaker007]

Thank you thank you thank you!

[dnxmy]

haha i want a manpurse too

[yuriurzhumov]

much. thank you sooo much



[yuriurzhumov]

i wish he was my chemistry teacher 

[HelloTherePepper]

ohmygod. youve helped me so much. thank you sooo much. i wish my teacher was 1/2 as good as you.

[woddaheck]

i do love you

[dkt081994]

you rock!

[007coolio007]

4 ppl failed chemistry before looking at this video!!!!

[MrAthanz]

This helped so much, thank you

[mabelle502]

You are just awesome. Please make more videos

[apagoogoo]

sounds like when venus flytrap was explaining atoms.

[thatswhatshesaid2727]

Thanks! But dude. I got a question. Like the atoms in the far up left of the periodic table are atoms with the least electrons in there outer shell right? like the ones in Group 17 and 18. They are very reactive. But in your video, its like your saying that they are not really reactive since they need a lot of ionization energy to react. Please help me out :(

[gaoyusi85]

I am preparing for a science test for my teaching certification. This is a truly inspiring lesson. thank you so much!

[dchen21]

ugh chem test tmr.. thanks for this video it was far from the typical boring lecture!

[dchen21]

ugh chem test tmr.. thanks for this video it was far from the typical boring lecture!

[zhanzack]

thx! =)

[om0333]

y do u keep lukn down? :O lol btw thnks for tht i will do my exam gud nw :D

[Lilllw]

Man great video. Very easy to understand and informative!

[ecgirll]

perfect, thanks

[w0sXs0w]

Bravo, very fun way to understand the concept. When the concept is achieved the technical will be as easy as eating a pie.

[gabannaania174]

You are such a genius!! I learned more from you in 10 mins than from my chem teacher for the past month!! Thank you so much!!!! :P

[michiyo002]

thank you so much for posting this video.. it helps alot thanks!

[masterdaiki]

Excellent!! Thank you^^

[dnnkbk]

yea, uhmm, ur going to need to be my new chem teacher. lol.. excellent tutorial

[kelin818]

i think it was good helped me with my hw alot.

[smilingpomme]

where do the electrons go ?

[xxjennyhere]

You've saved my Chemistry grade. MUCH appreciated! It's a fun way, and I understood eerything... and I disagree with the dude saying technical stuff is missing. Go get a book. :)

Thanks for the explanation!

[OrangeJuiceeee]

i love the way you teach. you make it way more interesting than my teacher, and i really enjoy your examples! thanks a lot!

[ftart]

this is a good way to explain it but perhaps you should consider giving the real answer with the examples. so it takes more inoization energy to remove electrons from left to right ok. why??? as you go from left to right, protons increases. protons attract electrons, holding them together more tightly. just a suggestion. no offence or negativity intended.

[tdewitt451]

@ftart yup, you're right. that's an important concept for sure. but it's always a delicate balance between telling part of the story and giving too much information. as a teacher, i find that if you give too much information at once, the whole concept is lost. if you were in my class, the next day after this lesson, i'd say, "now why do the atoms get smaller?" and we'd go from there. if you're interested in teaching (i hope you are!) a vital thing to think about is: "what can i leave out?"

[ftart]

@tdewitt451 i see your point. btw very good explanation and example! very thorough. i really like your teaching methods. please continue to post videos! i subbed. OH and i am interested in teaching. i my self am a student attending gr 11 so teaching would be quite a step from now. but if you dont mind me asking, how do you become a teacher besides getting really high grades? how many years in university and in teacher's college.

[thespartan95]

@tdewitt451 thank you so much im going to ace my exam tommorow my teacher was an ex-chemist so she uses techincal talk we you use something we can relate to like the stealing of the purse

[oAnderso]

This video is really really useful for my study.

You have used a more interesting way

to explain the concept of I.E. It makes me learn easier.

Thanks!

[deathcallblaze]

excellent video it make way more sense to me now!!!

[davidFbeckham]

Fantastic analogies! Thank you very much :)

[MsGeorgCH]

waw it's good. thanks for uploading

[AtlantiXYL]

college professor dont do this, instead they talk crap no one understand

[KraziAzian]

I LOVE YOU. I wish things were always explained in school using the simple terms and analogies, and then once we grasp the concept they can get more technical. But instead they just start out with technical and then its just plain harder for no reason.

[Ankitkp1]

Nice lecture very thanx 2 this video......

[paulamca]

wow! thank you so much! this is really impressive! cause i can totally understand your explanation but it seems impossible to get what my brazilian teacher tries to explain about atoms (i am brazilian too), haha.

[bevon17]

Thank you for putting it in simple terms = )

I appreciate the time you took to make this video

thanks!

[ymonkey333]

a 10yrs old would understand this!! thx

[riazsalleh]

good job

[nicolejb89]

THIS HELPED ME A WHOLE BUNCH CHEMISTRY IS TOO HARD THANKS FOR MAKING IT A LITTLE EASIER

[coldicce]

Atomic Radius

[edde8282]

what if i use a gun to take the purse away from the tough guy? and why does a tough thug guy have a purse?? i am so confused. :(

[mhae2006]

Thank you so much. This really help!

[ecualopezjg]

you made this so easy to understand...i love how you explain making it so easy to comprehend...plus good looks help too :p

[ecualopezjg]

you make this so easy to understand...love the way you explain it..plus good looks help too :P

[machacador28]

It's good to explain things like this to make people understand, but you need to be more technical! ;D

[tdewitt451]

@machacador28 i understand your point, but i have to disagree. youtube is not a good source if you need technical information; it's like going to mcdonald's and expecting gourmet french food. if you need to be technical, go to the library, or look through textbooks, or even wikipedia--they're all filled with technical information, but it's so boring and impossible to understand. what i'm trying to do here is to get the basics across so people can get it, and hopefully in a fun way.

[machacador28]

@tdewitt451 I also understand your point .... but i think it's better a combination of technical information and what you do, I mean, they are compatible. Anyway I have to congratulate you, because it's a good work, but, at least for me, it would be better if you went through the barrier of technical language.  xD

[funkyboy90000]

@tdewitt451 what sparked your interest in chemistry? I can tell that you have a genuine love of for science.

[Razor0507]

you ever thought about being a teacher?

[ryuuxhana]

OMG This used to look like alien language in my book but now it is sooo easy to understand!! Thank you very much!

[bignil05]

haha where did you get that purse? very helpful though. thank you

[bwalker4566]

Thank you so much! You're the man

[thatwarior]

where you people would live after throughing atomic bombs when after that there are ozone holes, ice mellts and children born degenerated?

[Corrodant]

Radius is the inverse proportional of Ionization energy.

going up and going right in the table will give a greater i.e. and vice versa

[ColourfulRaiin]

i finally get this crappppppp

[zelunika]

nice video...lol

[zelunika]

ist group elements have lower ionization energy coz it haz larger size zen the second group......second group haz higer than first ...and so on the third haz higher than the second...and at last wn we reaches the halogens which haz got the most higher ionization energy....but remember 1st group haz radious larger than second....and second group haz smaller size zen ze ist and so on at last wn we reaches halogens

[zelunika]

...the radious become very small as compared to 1st group.....as we move 4rm left to right the size decreases and so the charge density...as the charge density increases....its ionization energy also increases....

[ctrooper742]

great. keep it up

[27131014198743]

5 Star's for the purse

[mosheco69]

Bravoooooo

Thanks from Morocco

[dannimcr4eva]

Very helpful i have a chem test tommoro and i really need this! i was soooo lost thanx alot ur perfect! :)

[GabhrooShakeen09]

u guys have a crap definition. its the energy required to remove 1 electron from 1 mole of gaseous atoms to make 1 mole of gaseous 1+ ions

[abbeyzgray]

very good. the comparisons were very

well done. this helped me out a lot.

[zhsmediateam09]

you are hilarious! and a good teacher!

[ccri5548]

post more vids theyre real helpful

wow that was awesome...where are these teachers hiding?

[Soapatron]

you just tough me more then my chemistry teacher did in a week.. thank you. very good video. im not a very studious person n i cant concentrate very long but, i didnt want this video to end. very well put together

[dan020350]

I thought we were going to learn to steal ions, instead we get a description of ions. : (

[dan020350]

i want a video explaining about electro-magnetism.

[dan020350]

this beats free education in public schools.

[khbergstrom]

youre great! thank you! good job! much love from CCU, colorado!

[ksniper5]

awesome

[weinthacar]

THANK YOU SOOO MUCH!!

you have explained IE wayyy better than my chem teacher could have ever done it. You should really go into teaching if you already haven't. Haha love the "shriveled old lady and thug" analogy.

[dan020350]

i wish i could have seen a demonstration in microscopic scale.

[dan020350]

nice physics assistant

[ArchanaJega]

Amazing explanation.

[malissax16]

You explain things so well! I wish you was my chem teacher lol

Please make more videos =)

VERYYYYYYY WELL PUT... U SUD PUT MORE VIDEOS examples like this! I think I speak for everyone when I say *********Very easy to understand***** and thank you!

[dragonarts]

thank you ^-^

[FS201]

yo bro at first i was going to call you a retard lol, but then i actually listened to your video and man your actually a pretty sick teacher, better than my chemistry teacher that's for sure, so i just wanted to say thanks man cuz this will really help on my test tmrw, and keep it up man your good at what you do. good stuff mate.

[GolsangNaseri]

Thanks for the BEST explanation :-)

[alexandra20147202]

man, good exaplanation.i learned fast!

[kristmist]

I learned during this 10 min long video more than I learn in class putting all subjects together for say two weeks!!! Not only did you explain everything clearly, but it was simply interesting, which is a vital part of learning!!!

[wenzjayy]

hey!!!! thank you very much!!!! youre not just a good teacher... youre also cute!!!!! hey how to steal your dick!!!! i love it

[ljmiffl199511]

Thanks for breaking that down to laymen terms ;)
