Solution

The correct option is D 16
We know, value of ml varies from l to +l.

For ml= +1, minimum value of l= 1.
l= 1 corresponds to p-orbital and each p-subshell has 2 electrons with ml value +1.

So, we need two p-subshells in order to have 4 electrons with ml=+1.

1s22s22p63s23p4 have 4 electrons having ml=+1.

Therefore minimum atomic number of element having ml=+1 is 16.
