(a).
28
(b). 8. 2.1 (c) 2. 18 (d).
28. 1​

Answer 1

Answer:

Option (d): since the atomic number of sodium is 11 and K, L, M shells can have maximum 2, 8, 18 electrons respectively. Therefore the correct electronic configuration of sodium is 2, 8, 1 where K shell has 2 electron, L shell has 8 electrons, M shell has 18 electrons. Therefore this option is correct.
