In a ground state atom of Br how many electrons total will have the quantum number l=2?
Please provide explanation.
Pauli Exclusion principle states that no two electrons can have the same quantum numbers. Each electron has a specific set of unique quantum numbers.
The electronic configuration of bromine atom is;
"1s^22s^22p^63s^23p^64s^23d^{10}4p^5"
It's principal quantum number is "4.33"
Quantum number "l=2" corresponds to d level only
The total number of orbitals "=4*10" electrons
"=40" electrons.

4x10= 40 electrons. Where did you get the 4 from?
