Here's my question. In B- decay, the end result in gaining a proton and losing an electron+neutron. In B+ decay, you lose a positron and gain a neutron, do you also gain an electron? Also in electron capture (B capture) you gain an electron and lose a proton to gain a neutron and for B+ capture you gain a positron and lose a neutron to gain a proton. I guess the general question is, when you are gaining and losing protons you are changing the atomic numbers. However, are you also gaining and losing electrons so that your product is the elemental (non-charged) form instead of having some sort of ion?
