Solution

The correct option is C protons, electrons
Atomic number is the number of protons in an atom. In a neutral atom, the number of protons is always equal to number of electrons. So, atomic number is not just equal to number of protons but also number of electrons in a neutral atom.

Atomic number (Z) = Number of protons = Number of electrons
