The element nickel has 28 protons, which means, it has 28 electrons as well since the number of electrons is the same as that of protons.
Since the relative atomic mass(Ar) of Nickel is 58.7, the number of neutrons it has should be (58.7-28), which makes it 30.7.
*Relative Atomic Mass=Number of proton+Number of neutrons* Mass of electrons is considered as negligible.

Nickel has atomic number Z =28, so a nickel atom contains 28 protons and 28 electrons.
There are five stable isotopes of nickel, with mass numbers 58, 60, 61, 62, 64, which contain 30, 32, 33, 34, 36 neutrons respectively. Most abundant is the Ni-58 with 30 neutrons.

look at the periodic table of elements it will tell you there are the same amount of electrons as protons
