The ground state electronic configuration for sodium is 1s²2s²2p⁶3s¹.What is the orbital quantum number of the last (3s¹)electron? A)3 B)1 C)2 D)0

Question

Quizplus · Accepted Answer

The orbital quantum number (l) determines the shape of the orbital and is related to the subshell type (s, p, d, f). For an s orbital, l = 0, regardless of the principal quantum number (n). Since the last electron of sodium is in a 3s orbital, the orbital quantum number is 0.

The Ground State Electronic Configuration for Sodium Is 1s22s22p63s1

The Ground State Electronic Configuration for Sodium Is 1s²2s²2p⁶3s¹
