Chemistry Tutorial 3.01a: Atomic Structure - The Nucleus

[batisok]

THANKS ALOT this video was very helpfill to me

[MySpykee]

Very interesting, and 'classical'. There are some questions I have not been able to get answers to (or if i do get answers they are so jargon riddled as to be worse than useless).

1) I am lead to believe neutrons stabilise Protons from flying apart due to their like charges. But Neutrons don't have charges, so they should hang together due to nuclear attractions alone. Why can't you have groups of neutrons as stable nuclei?

2) How do I make sense of the NOT 1:1 ratio of protons:neutrons?

lol @ "this will come in handy later in the year". He's really in teacher mode.

you my friend are awesome teacher :) ty!!!

DEAR VIEWERS,

FOR ASTONISHING FACTS ABOUT SCIENCE, JUST TYPE IN THE SEARCHING BOX:

Quran snd Science

SEVEN PARTS! YOU MUST LIKE THEM!

[WarmSweetYoda]

you're the best mark! if i have you as my chem teacher i would probzably had pass 17years ago lolz. Now i'm back to school and studying from you

[abhinavjoshi14914914]

But 7000 protons will have mass of 1007....but a charge of 1000 lol

[LondonSky08]

Thank you so much!!!

[praizorr]

THANKS SO MUCH! do more videos! i've been trying to understand this since september last year!! finally got it! thankyou again :D

[j3nnaviv3wlliams]

hello i need help with my science work what is the The basic structure of a metal?

please reply,

thanks :)

[shino200621]

Nice one! Thanks :D

[koppen123]

Isn't there a fourth hydrogen called protium, or hydrogen-1 as well?

[MarkRosengarten]

@koppen123 H-1 is protium, H-2 is deuterium and H-3 is tritium.

[PenguinMan272]

Unbelievably helpful, thanks

[aygachu]

haha the way you speak. love the effort.

[brookes641]

Great video, thanks!!

[arbaaz94]

thanx a lot MARK :) it helpd to clear my lil brothers chem doubts :)

[Hongkster]

thank-you. this video gives insight and breaks the concepts down to produce a simpler and more understandable lesson.

[MultiPlacencia]

very simple and understandable..... gratziii!! 

[abhishekumar94]

hey this video has madde me more confused abt the atomic structure ...

[camzie1504]

Thank you! You've made this so easy for me to understand.

[MrHitlife]

good video got a good undrstanding of it in a basic way way better then my teacher thanks.

[MrChristar69]

Thanks very much!! Great video

[soontobewcso]

Thanks for the educational videos

[seansDOTme]

props

[bluefogtree]

thaaank you

[balletrocks92]

I have doubts, what I wanna ask is that why some teachers gave the definition of isotopes as atoms of the same element which has different nucleon number (instead of using neutron)? Is there significant differences?

Thanks for the videos :)

[ddfgg42]

different numbers of neutrons will change the nucleon number(mass number).so they do have different nucleon numbers.i think thats the case

[Sherwah1]

Neutrons+ proton= Nucleon number(Ar), so when the neutron number changes the nucleon number(Ar) also changes.

[gurusomb]

@balletrocks92 it means the same thing- just differently expressed. The first one is the mass number (protons+neutrons) and the second is just the number of neutrons. Both change depending on the number of neutrons :)

[justanotheraustrlian]

im new to chem and i REALLY needed this

thank you so much!!

[Sherwah1]

Good! It may be good to join groups on yahoo etc and read more.and dont forget to practise past papers!

[aahatch]

gcse mocks next week :P

[aishumadz]

thanks a lot it was really very helpful for my term exams.

[ZoeVivi]

excellent work! that was a LOT of help.

[omegared339]

this was perfect! exactly what i needed. thanks.

[jacqulene]

Thank you : )
