Question

How many subshells are present in 'N' shell?

• A. 2
• B. 4
• C. 3
• D. 1

Answer 1

Answer:

B. 4

The 'N' shell corresponds to the principal quantum number n = 4.

• Subshells:

For n = 4, the possible values of the azimuthal quantum number l are 0, 1, 2, and 3.

• Subshell Notation:

These values of l correspond to the following subshells:

• l = 0: 4s

• l = 1: 4p

• l = 2: 4d

• l = 3: 4f

  Number of Subshells:

Therefore, there are 4 subshells present in the 'N' shell.
