Chapter 6: Q6.9CYL (page 310)

How many orbitals havel= 2 andn= 3?

Short Answer

Expert verified

When n=3 and l=2, then it represents 3d- subshell.

3d-subshell has five orbitals.

Step by step solution

01

Shells and subshells

The value of “n” represents the principle quantum number. It represents the size of the orbit/shell.

Quantum number l represents the shape of orbitals.

l = 0 represents s- subshell and it has one orbital.

l = 1 represents p-subshell. p-subshell has three orbitals.

l = 2 represents d-subshell. d-subshell has five orbitals.

l = 3 represents f-subshell. F-subshell has

02

The number of orbitals in a subshell

The “n” and “l” values of the given subshell are: \(n = 3,l = 2\).

These values represent 3d-subshell.

The d-subshell has five orbitals.

Hence, the answer is five orbitals.
