As given no. of protons is 8 so the atomic no. would be 8... As no. of protons and no. of electrons are equal so the atom will be neutral...

(i) Atomic Number will be 8 (ii) As electrons and protons are equal, the atom will be neutral
Comments

i) The atomic number is equal to the number of protons. Therefore, the atomic number of the atom is 8. (ii) Since the number of both electrons and protons is equal, therefore, the charge on the atom is 0.

Atom 8 and charge 8 multiply total charge on one electron.

The atomic number will be 8 because an atomic number is equal to the number of protons. And the atom is neutral as it has 8 electrons and 8 protons.
