Proton number is the same as the atomic number.Co has atomic number 27
Hence it has 27 protons

In a neutral atom the electrons equals the protons but this is an ion (cation that has given out 2 electrons) and so has electrons being (27 - 2)= 25

Neutron number is the difference between the mass number and proton number.i.e neutrons = 62-27 =35

Protons = 27
Electrons = 25
Neutrons = 35
