what is the correct representation for the subshell with n = 2 and l = 1? 2p 1p 1d 2d

Brief Explanations:

In atomic - orbital notation, the principal quantum number (n) represents the energy level and the angular - momentum quantum number (l) represents the sub - shell. When (n = 2), the possible values of (l) are (0) and (1). When (l=0), the sub - shell is (s); when (l = 1), the sub - shell is (p). The notation for a sub - shell is (n) followed by the letter corresponding to (l). So for (n = 2) and (l=1), the sub - shell is (2p).

Answer:

2p
