Beta decay | Physics | Khan Academy

During beta minus decay, a neutron in an unstable nucleus transforms into a proton, releasing a high energy electron and antineutrino in the process. During beta plus decay, a proton in an unstable nucleus transforms into a neutron, releasing a high energy positron and neutrino in the process. Beta particles carry away energy lost by the nucleus and are ionizing radiation.

You can tell the teacher’s enthusiasm from the way he teaches!😃

[@someone90179]

Yes indeed he makes it very clear

[@carlosvellu1744]

That child like Wonder.. That strong sense of awe😍.. absolutely love Science when it's approached with passion ❤️💯

[@HakanPeker7]

It's the first time I learned something about chemistry. It's a good channel.

[@Random-bro-______-RaNdOm]

This vid is amazing, but pls upload gamma decay also soon, plsss

[@malekqaddarah]

Mahesh sir do u work now with normal khan academy?amazing!

[@malekqaddarah]

@@9-volt247yes he works with khan academy India. Amazing tutor!

[@tirthalily]

This was so simplified and well explained. Thank you!

[@someone90179]

Thanks for teaching us! You have made it very clear! Keep it up!

[@eleanorfarrashzadeh881]

I love how excited he is to teach us about this it's so cute and makes me excited and interested to learn😊 alpha beta and gamma radiation and their real life application is so fascinating

[@user-kf4nw3hs3r]

شكرا جزيللا على هذا الشرح المبسط والمنظم ^^

[@dhairyajaiswal5394]

Lovely explanation sir ❤

[@someone90179]

The positron is the electron’s antiparticle right?

[@TheJoaveck]

Around 6:00 You talk about a Positron. You say it has the same mass of an electron but the Mass number of the daughter didnt change. Whats the explanation for that? Protons and Neutrons have the mass, right? So when the Proton turn into a Positron it should have less mass, right?

[@descendingDark]

what a positron is is a tiny particle that carries a +1 charge, but no weight. so imagine that a proton= neutron+positron

[@dikshilpatil7317]

What properties do anti neutron have?

[@someone90179]

Isn’t the positron the electron’s antiparticle?

[@malekqaddarah]

What difference between neutrino and anti neutrino if they are neutral in the first place?

[@dockhunter6353]

They help balance out the Lepton number (sort of like another charge), which are what electrons and positrons are made of. Lepton number is +1 for any particle and -1 for any anti-particle. Hence, if a positron is emitted (which has a lepton number of -1), we need to add a neutrino (+1 lepton number) to balance even further
