What are the possible values of principal (n) and azimuthal (l) quantum number for the unpaired electron in the atom of an element whose atomic number is 9 ?

What are the possible values of principal (n) and azimuthal (l) quantu

1.	What are the possible values of principal (n) and azimuthal (l) quantum number for the unpaired electron in the atom of an element whose atomic number is 9 ?
Answer» SOLUTION :`._(9)F = 1s^(2) 2s^(2) 2p_(x)^(2) 2p_(y)^(2) 2p_(Z)^(1)`. Hence, for the UNPAIRED `2p_(z)^(1)` ELECTRON, `N = 2, l = 1`
