Question

The total number of atomic orbitals in fourth energy level of an atom is:

A

16

B

32

C

4

D

8

Step-by-Step Solution

The total number of atomic orbitals in a principal energy level (nn) is given by the formula n2n^2.

For the fourth energy level (n=4n=4):

  1. Formula: n2=42=16n^2 = 4^2 = 16.
  2. Detailed Breakdown: The fourth shell consists of four subshells: s,p,d,s, p, d, and ff. 4s4s: 1 orbital 4p4p: 3 orbitals 4d4d: 5 orbitals (Referenced in Unit 4, d-block elements) 4f4f: 7 orbitals (Referenced in Unit 4, f-block elements)
  • Total: 1+3+5+7=161 + 3 + 5 + 7 = 16 orbitals.

Note: The maximum number of electrons would be 2n2=322n^2 = 32.
