Nickel have 28 protons and electrons and a different number of neutrons for each isotope..
Nickel is a metal and has 28 electrons when not ionized.
Nickel has 28 protons; thus, it has 28 electrons.
Nickel has 28 electrons when it is neutral, however the Iron(II) ion has 28 electrons as well.
A nickel ion with a +2 charge has lost 2 electrons. Since the atomic number of nickel is 28 and it is now a +2 ion, it has 26 electrons remaining (28 - 2 = 26).
Nickel has two unpaired electrons.
