Question

The maximum number of electrons that can be accommodated in the L - shell of an atom is : [ 1 Mark]

(a) 2
(b) 18
(c) 8
(d) 4

Answer 1

The correct answer is (c) 8 electrons.

• The maximum number of electrons that can be accommodated in an energy level is 2n² (n = number of its orbit, for K=1, L=2, M=3).
• So, L shell can accomodate = 2 x (2)² = 8 electrons.
