Question

Which of the following orbitals has one angular node and one radial node?

• A. $2s$
• B. $2p$
• C. $3p$
• D. $3d$

Answer 1

The correct option is C $3p$

The number of radial nodes = $n-l-1$
Radial nodes in $3p$ = 3 - 1 - 1
= 3 - 2 = 1
Number of angular nodes for any $p$ orbital = 1
Angular nodes in $3p$ = 1
