Solution

The correct option is C (i) and (ii) represent different elements
The option (C) is the false statement.
(A) Energy is required to change (i) to (ii). An electron is excited from 3s orbital to 4s orbital.
(B) (i) represents 'Na' atom having atomic number 11 and total 11 electrons.
(C) (i) and (ii) represent ground state electronic configuration and excited state electronic configuration of same element.
(D) More energy is required to remove one electron from (i) than (ii) as in (ii), the outermost electron is farther from nucleus and loosely held.
