Principal quantum number defines the principal shell in which electron

1.	Principal quantum number defines the principal shell in which electron is revolving around the nucleus and Azimuthal quantum number describes the name of subshell and the shape of orbitals. The value s of the principal and Azimuthal quantum number for 23rd electron present in iron atom are :(a) 3 and 2 (b) 3 and 1(c) 4 and 1 (d) 4 and 0
Answer» Correct Option (a) 3 and 2 Explanation: Electronic configuration of Fe is [AR] 4s²3d⁶The 23rd electron will enter in 3d subshell Hence, value of n for 3d = 3 value of l for 3d = 2

Answer»

Correct Option (a) 3 and 2

Explanation:

Electronic configuration of Fe is [AR] 4s²3d⁶The 23rd electron will enter in 3d subshell

Hence, value of n for 3d = 3

value of l for 3d = 2
