Give the number of protons (p), electrons (e), and neutrons (n) in one atom of nickel-62. a) 28 p, 28 e, 28 n b) 28 p, 28 e, 34 n c) 28 p, 28 e, 62 n d) 62 p, 28 e, 28 n e) 62 p, 62 e, 28 n

Explanation:

We need to find number of protons, electrons and neutrons in ⁶²Ni

Mass number is 62.

That is

       Number of proton + Number of neutron = 62

We know that number of proton = 28 for nickel

So

       28 + Number of neutron = 62        

        Number of neutron = 62 - 28 = 34

We also know

         Number of protons = Number of electrons

          Number of electrons = 28
