Q: 7/4 Be goes through electron capture to result in?

Shouldn't the answer be 6/3 Li? If you add an electron then the protons decrease by 1 (4 to 3) and the mass number decreases by 1 because you have one less proton right?

proton captures electron, gets married and becomes a neutron

^round-about way to say that the mass doesn't change. So yea it results in 7 + 0 = mass of 7; 4 + (-1) = 3 protons.
