Question
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 ?
(ii) What is the charge on the atom?
Solution
(i) Atomic number defined as the number of protons present in nucleus. Also, number of protons are always equal to number of electron. Thus atomic number of atom is 8.
(ii)Since, there is no gain or loss of electron in atom. Therefore charge on the atom = 0.
