Question

When carbon-14 undergoes beta decay, it becomes which of the following?

Answer 1

beta decay (-1 e) it means that the molecules gain one proton

if you check in the periodic table, the atomic number of carbon is 6. if you add a proton, it becomes #7 which is nitrogen (N). the atomic mass stays the same.

I have attached a drawing showing the reaction.
