In striking contrast to alpha decay, the electrons (minus or plus charged) emitted in beta-minus and beta-plus decay do not exhibit sharp, ... First, as the nuclear charge Z increases, the relative probability of low-energy electron emission increases by virtue of the coulombic attraction.

WebbSo A is the mass number, which is equal to the number of protons, that's the atomic number which we symbolized by Z, plus the number of neutrons. So A is equal to Z plus N. And for protium, let's look at protium here. So in the nucleus there's only one proton and zero neutrons, so one plus zero gives us a mass number of one. Webbdifferent charges. You probably know that the word "'charge" has some- thing to do with electricity. There are two kinds of charges. There are positive (plus) charges and negative (minus) charges. By studying atoms, scientists have learned that: PROTONS have positive (+) charges. ELECTRONS have negative (-) charges. NEUTRONS have no charges.
