Text Solution

Verified by Experts

The correct Answer is:
A,B
`._26Feto1s^2,2s^2,2p^6,3s^23p^6,3d^6,4s^2`
`{:(l+m=0implies,l=0,m=0,i.e.s-"subshell"),(,l=1,m=-1,i.e."one orbital of p"),(,l=2,m=-2,i.e. "one of d-orbitals"):}`
hence there are 13 or 14 electron as in d-orbital it may be one or two electron having m=-2
