Answers

(i) Atomic number = Number of Protons = 8

(ii) In the given atom, total number of positive charge is equal to the total number of negative charge.

Number of Protons (8) = Number of electrons (8)

So, the charge on the atom will be zero.

 
Concept insight: Recall the formula of atomic number. Also, remember that the charge on proton is +1 and that on electron is -1.
