If number of electrons in an atom is 8 and number of protons is also 8, then (i) what is the atomic number of the atom ? and (ii) what is the charge on the atom?

Q.:- If number of electrons in an atom is 8 and number of protons is also 8, then
(i) what is the atomic number of the atom ? and
(ii) what is the charge on the atom?

 

Answer:-

We know that,

No. of electrons (e) = No. of protons (p) = Atomic number (Z)
(i)   No. of electrons = 8
Therefore, Atomic number = 8
(ii) The number of protons is equal to the number of electrons. So the atom will be neutral.
