[ ] number of electrons as those are revolving around nucleus and in an atom electron number is same as number of protons

Solution

Answer- number of protons as those are present in nucleus and is equivalent to number of electrons revolving around nucleus

number of electrons as those are revolving around nucleus and in an atom electron number is same as number of protons
