Question

What designation is given to orbital having n=3, l=1, m=-1

Answer 1

Explanation:

Since the electron is unpaired, all the orbitals before n=3,l=1 are filled. Now, for principal quantum number n, the number of electrons are n=2n

2

. Therefore, the minimum number of electrons in the system =2+8+2 (electrons in n=3, l=0) +1 (extra electron).

Therefore, the atom is aluminium. Silicon and phosphorus can also be the possible solutions to this problem.
