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.

The positron is the electron’s antiparticle right?

@TheJoaveck 4 ай бұрын

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?

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

What properties do anti neutron have?

Isn’t the positron the electron’s antiparticle?

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

@dockhunter6353 3 ай бұрын

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
