In an ionic bond, one atom give electrons, while another atom recevie electron. Because of that, this is the better option to metal cations.
D. To answer this question refer to the periodic table and think logically about it. Adding one proton increases the atomic number so you go along the row to Nitrogen. If you lose one neutron then the atomic mass decreases by 1 so 14-1 is 13.
thx but it's actually 143
