The number of electrons accommodated in an orbit with principle quantum number 2, is

View answer and explanation

Correct option: D

8

Option D (8) is correct because the number of electrons accommodated in an orbit is given by

2n^2

, where n is the principal quantum number. For n=2, the number of electrons is

2(2^2) = 8

.
