Beta decay can also be caused by the emitting of a positron. The antimatter equivalent of an electron. Same mass but a positive charge instead of a negative charge.
Does anything change in a gamma decay equation if nothing was excited in the first place? So like in the example you used, if the technetium wasn't in an excited state, would it have just gone from 99/43 Tc to 99/43 Tc? Or would it have went backwards, like 99/43 Tc to 99m/43 Tc?
@Orchestra Of Ruin, I don't believe you are right. Positron emission and electron capture are usually grouped together as two possible courses of action when a proton needs to convert into a neutron to stabilize the nucleus. Beta decay and positron emission are the result of different conditions, namely when a neutron needs to convert into a proton and when a proton needs to convert into a neutron, respectively. Therefore I believe your statement that beta decay can also be caused by the emission of a positron is incorrect. Please correct me if I am wrong.
In beta(-) decay, where do we get the extra valance electron from? If Electrons=protons, and we are gaining one proton, while ejecting one electron..unless we are forming a cation does this mean we are also creating one valence electron? So a Neutron becomes a proton, electron, & a valence electron, for a total of 2 electrons?
When the neutron decays in to a proton. The neutron doesn't immediately radiate an electron. It actually radiates a W-particle, which decays into an electron and an anti-electron-neutrino

literally my chem teacher doesn't teach so thank you so much for this
Wow u explained that so much better than my lecturer
Carly P agreed
Did you pass? I'm doing an experiment were I ask what has come of people after they comment on helpful educational video for school
How's life been 5 years later?
I can’t wait for the day where I will use this in my life!
It's sure to come soon!
Thanks so much I cried
Angelina Soleil why

@@robhousehold I didn’t I’m homeless and have no job even after going to Harvard with a 4.5 gpa with sports

oh yea
but then electron decay in antimatter

My Chem teacher is awesome but I didn’t understand all this time and I have a quiz tomorrow. I’ve joined the club

This makes me hate my teacher even more because of how simple it could be to teach
thanks. it helped me a lot
You saved so many lives that you might we might as well call you super man, but PLEASE talk louder even though this video came out in 2014.
Thank you sm
Khan... what happened to your voice?
KHAAAAAAAAAAANNNNNNN

How would i represent both equations in one equation
thank you
U're awesome
What if you're given an equation, but you DON'T know which decay to apply to it??
Tiff ikr...I have a quiz on tuesday and don't know if my teacher just going to give me the equation and nothing else
whats the point in knowing this... :/
word
WAIT........YOU ARE NOT Mr.SAL KHAN OR NOT THE OWNER OF KHAN ACADEMY...........WHY??
Alina Turak still teaches good
5:30 I don't understand how you got 0 there sorry haha could someone please explain
Because the equation was already balanced. They both had a 1 so therefore he didn't have to add anymore.
didn't understand
My science teacher is actually garbage if I compare this video to his teaching.
TALK LOUDER
