How many electrons belonging to an atom of 13Al are associated with the azimuthal quantum number (ℓ = 1) under ground state condition?
A. 4 B. 5 C. 6 D. 7 E. 8
can anyone explain why the answer is D.

An azimuthal quantum number of 1 refers to electrons in the p orbital. Aluminum has 6 electrons in the 2p orbital and 1 electron in the 3p orbital. 6+1= 7 total electrons.
