Help with finding the amount of protons, electrons and neutrons?
Consider a hypothetical case in which the charge on a proton is twice that of an electron. Using this hypothetical case, and the fact that atoms maintain a charge of 0, how many protons, neutrons, and electrons would a hydrogen-2 atom contain?
I don't understand how can I know the amount of protons, electrons and neutrons. don't give me just the answer please explain it.
