Question

An atomic orbital has two angular nodes and one radial node. It is a:

• A. $2p$ orbital
• B. $3p$ orbital
• C. $3d$ orbital
• D. $4d$ orbital

Answer 1

The correct option is D $4d$ orbital

Two angular nodes are found in d-orbital (Angular node $=l$) for a d-orbital to have one radial node it $4d$.

[$\because$ Number of radial nodes $=n-l-1$]

Hence, option D is correct.
