Answer
Given: Number of electrons = 8
Number of protons = 8
(i) The atomic number of an atom is the same as the number of protons in that atom; hence, its atomic number is 8.
(ii) In an atom, the number of protons is equal to the number of electrons. Hence, both the charges – positive and negative – neutralise each other. Therefore, the atom does not possess any charge.
