A principal shell having the highest energy subshell to be 'g'can accomodate electrons to a maximum of .

Options

A. 18
B. 32
C. 25
D. 50

Answer

D

Explanation

For .g. subshell , l = 4 . The minimum value of principal quantum number n = 5 . No. of orbitals in 5th shell `5^(2) = 25` , No . Of electrons `2 n^(2) = 2 xx 25 = 50`
