Given below are the quantum numbers for 4 electrons.

A. n = 3, = 2, m 1 = 1, m s = +1/2

B. n = 4, =l,m 1 = 0,m s = +l/2

C. n = 4, = 2, m 1 = -2, m s = -1/2

D. n = 3, = 1, m 1 = -1, m 2 = +1/2

The correct order of increasing energy is :

D<B<A<C

D<A<B<C

B<D<A<C

B<D<C<A

Text Solution

Verified by Experts

The correct answer is:

Energy order of subshell decided by (n+ ) rule.

A 3d n + 1 = 5

B 4p n + = 5

C 4d n + 6

D 3s (n+ ) = 4

D<A<B<C
