What is radioactive decay? Simple Explanation

[MrAfglondon]

this was very simple and lovely .. u just explained it widelly and injected to my brain .. thanx to whoever you are .. thanx thanx

[orbazel]

Please YouTube! Please stop kids from posting incorrect video's as other kids use these videos to learn it and do their homework from as they can't be arsed picking up a book. Your single handedly breeding retarded kids who won't have a clue how things work.

Imagine a kid comes along and watches this, makes his own video with his own mistakes in it, six kids and six video's later and we've then got pink elephants smashing into each other creating a chain reaction of bubble gum.

[300duoplus]

you sounded as if you didn't know what you were talking about

[medialover661]

exactly i didnt understand shit

[nofatchxplzthx]

you need to explain why the element decays and HOW it is unstabble, i already know why but others may not know

i dont wanna get too technical so here is a short summary

the force that holds the atoms together is weaker than the force that repels them apart

[ujayet]

@nofatchxplzthx "the force that holds the atoms together is weaker than the force that repels them apart" excuse my ignorants.. but why or how did it stick together in the first place?

[stephengonzales1]

@DarthHater100 Your still wrong, half-life is the awesomest video game ever

[DarthHater100]

At 0:50 you say: "Half life is the time that it takes for half of the atom to decay. . ." Half life is NOT the time for half an atom to decay. It either fully undergoes decay or it doesn't, half life has nothing to do with half and atom decaying. A single atom cannot half-decay. Half life is when half the unstable nuclei in a substance have decayed and the other half has not yet decayed. Sorry FAIL.

[alltiedup217]

@DarthHater100 darthhater is shockofgod and is a dishonest troll

[bradpara3782]

hey don't listen to these dickhole douchebags mate i thought u gave a pretty good explanation thanks youve helped me alot.

[willwallace888]

half-life is the time it takes for half of any given quantity of atoms to decay, not half of each individual atom.

[MegaBEANER1000]

r u a girl or a boy either way your voice is fucking irritable i doubt ul evr find an attractive girl freind soundin like dat

[edalzebu]

justin bieber did this video.

[VisRuu]

you have such a cute voice!

[HeavenHHeLL]

are you kidding me ... if someone explains anything like that I wouldn't understand a thing. I am wondering if the speaker even believes in what she's talking about.

[HeavenHHeLL]

[TiminPhoenix]

Wow, talk about a lot of punks making comments against the poster.

[MrStupidfag]

thank you for this

[moyaish]

too simple



[morr42]

im not a scientist or any thing but wouldn it be possible to re program a micro wave oveno power all the planet and we could maby also get free sat nav and sport utility vechicals

[Marchiu5]

is that boy or girl voice ?

[dzarren]

"half an atom" cannot decay.,

[raydoactive]

I hate unstability! 0:42

[kyle3420]

the half life does not have anything to do with individual atoms. It is defined as the time required for a radioactive substance to lose 1/2 of its radioactivity. This means that when there is a known amount of radioactive substance, after 1 half life the activity will be exactly half of what there was originally. There is absolutely no way of knowing when a single atom will decay. It is simply impossible.

[sovietspyguy]

You aren't explaining things in a simple way to the benefit of anyone.

You are explaining things that are clearly new to you, and that you don't have a good grasp of. This is obvious by your use of vague and incorrect terms, and the general tone in your voice.

On the other hand this is better then most videos young kids post, so kudos. Just don't think you're ready to be the teacher quite yet.

[gennkill]

why do you keep reading crap wrong!

[IronLion141]

Terrible explanation. I am only more confused and now will fail my exam.

[100rbunny]

then find another video and move on, if u werent a dumbshit u wouldnt be here to start so stop commenting.

[chesterngiamzhenghao]

this little kid just reads off from information. What he read was exactly most of it from a particular site. Faggot faggoty guy noob

[TheHomelessCripple]

This really didn't explain alot

[BIGBalls136]

im sorry but you just sound like a smart arse try to explain shit that you just dont hae a clue about.

[sajstyles]

that is so fucken gay

[wondergirlsy]

people are so mean here

[azcolvin429]

Wtf this didn't explain shit!?

[equalitydem]

Thank you for the video!

[loso74123]

Fucking Miracle.

[thedrewmo]

0:42 , lol, unstability, its instability

[Quadruplator]

He/She sounds kinda nervous and really missed out on a lot of important stuff about radioactive decay.

[theREALiceveela]

if you reverse the process, lets say zinc, has a half life of 145 years, so if i went back and time 145 years, my zinc would have doubled right?

[beestonbash]

@theREALiceveela no other way round, so if zinc has a half life of 145 years then the number of radioactive atoms in the zinc would have halfed.

[theBritzed]

very incomplete

[AJAYJOSHI1111]

This not a complete explanation of Radioactivity buttttt ok. not bad Good try..

[hxasmirl]

i believe there are plenty of research to be done on the subject. we are just beginning to understand a whole world of radioactivity

[222westlane]

No, the half life is not the time it takes half of the atom to decay but is" The time required for one-half of a given material one-half of any quantity of identical radioactive atoms to undergo radioactive decay

[gareler]

what kind of radiation does it emmit?

[D0g63rt]

Well thank you for blowing out my speakers.

[MicrosoftsourceCode]

I know what you were trying to say but it came out all fucked up. What do you mean a particle? A particle of what. And why is the element unstable?

[Crakamatt]

He already said it was Urainium 235.

[vfnk]

alpha, gamma, beta..also in states of consciousness...thank you for this

[vfnk]

adam?

[TheMrRandall]

Erm.. the problem is you say some fundermentally incorrect things... the radiation is the particle for a start.

[pyrot3chs]

Well, in the case of this video the atom shown is un-named, and can therefore be giving off alpha and beta radiation, which is the particle itself, or gama radiation which is just a ray of energy, so it can go either way

[baeronautics]

@pyrot3chs how old r u?

[IvanderHaisley]

@pyrot3chs uhm .. actually .... gamma rays are particles of light ..... light by the way contains energy therefor is not a form of energy .... light is made of a particle known as photons ...

[xRumpusx]

@pyrot3ch your comment is gibberish

[Scat495]

Im doing a project on the Atomic Bomb for History Fair, so this should help me understand how the Uranium235 is used in the Atomic Bomb.

[coopmen]

At least he tries, lets hear your explaination on radioactive decay, make your video about it and post. I would like to see it.......

[killarcha]

Don't explain shit you do not understand. I hate kids like you who attempt to explain such a concept and fail horribly.

Radioactive decay is not simple. I assure you it utilizes far more elementary physics and mathematics than you are capable. Furthermore, you know nothing of simple quantum mechanics... nor of simple expoential decay.

[Blackops981]

take a chill pill dude

[pyrot3chs]

No where did i mention that this was "simple", only rather the entire concept. Not to mention that of course i didnt go in depth becasue 99% of the youtube community is far too undereducated to grasp such a subject. this is a general overview, not a college lecture...

[killu19]

@pyrot3chs Do I smell arrogance? Comments like this don't create friends.

[baeronautics]

@pyrot3chs got a question for you when we bombard a neutron on uranium it gives off 2 neutrons+ba+kr+energy so my question is if we want to quicker the process is it possible to release 4 neutrons instead of two giving off two other minor elements different than ba and kr ?

[2high2aim]

@pyrot3chs Shut the fuck up and get serious haters. Yes, I have elevated diction and can confuse the fuck out of you just by vocabulary words but I am trying to learn and got sidetracked bc I read some of the bs comments. This kids trying his best to help and if the information is wrong than why the fuck dont you make a video yourself and explain to those of us that are searching for knowledge. Anyways thanks for your time even though this video did not help me I am sure you helped a few others.

[MrMadness87]

@2high2aim i gave you mom elevated diction

[TiminPhoenix]

@MrMadness87 If you are trying to make a one sentence clever witty comment, blowing the word "your" and putting down "you" instead leaves you looking like the idiot.

By the way, I'm sure it's not the only thing you blow.

[MrMadness87]

@TiminPhoenix ehem clever boy, where im from "your" sounds the same as "you", its slang you wouldnt understand. i dont care if it sounds out of context. my comment was funny, i dont care if you didnt think it was funny.my mom ses im funny so i am

[TiminPhoenix]

@TiminPhoenix If where you are from Your sounds like you, then you must be at some State Hospital for "Special Needs Kids." And your mom only says that, because the same LSD that caused your birth defect causes her to laugh at your comments, the weather report, the sound of paint drying...

[lilwoowoowoozie9242]

@pyrot3chs you actually did, @0:31

[SparkySubie]

Is light produced during this process? Or in any other small scale decay / irradiation devices?

[killarcha]

There are three different types of decay:

Alpha

Gamma

Beta +- (positron/electron emmitted as a proton/neutron becomes a neutron/proton + of course, a neutrino )

emag produced, thus light could be produced, though most of the photons have a far higher frequency as their kinetic energie (hf) must be great.

[phantaros]

Since when is "beta" pronounced "bayta"?

In Greek it's pronounced veeta! and in proper English (i.e not UMERICAN) it's pronounced beeta! (which is much closer to the Greek!)

[pyrot3chs]

Well, im sorry for mispronouncing it but beta is often pronounced the way I said it, and it doesn't really matter.

[xnrcsx]

Don't apologize for that. These people are such losers that they can't even find a creative way of insulting you, so they point out your mispronunciation .

however, I agree that you can't simplify quantum mechanics.

[Zockerfreak112]

That is really good explained and an interesting topic, too! Good work!

Five stars!

[pyrot3chs]

well, i understand what you are saying, i worded that wrong, it is how long it takes half of a given sample to decay

[bluequiltedness]

I thought that halflife was the time it took for half of any given population of atoms to decay, not "half of the atom to decay."
