Question

The number of radial nodes in 3s and 2p orbitals, respectively are

• A. \( 2 : 2 \)
• B. \( 2 : 0 \)
• C. \( 0 : 0 \)
• D. \( 3 : 2 \)

Hint:

Radial nodes formula: \( n - l - 1 \). Quick reference table: \[ \begin{array}{|c|c|c|c|} \hline \text{Orbital} & n & l & \text{Radial nodes} \hline 1s & 1 & 0 & 0 2s & 2 & 0 & 1 2p & 2 & 1 & 0 3s & 3 & 0 & 2 3p & 3 & 1 & 1 3d & 3 & 2 & 0 \hline \end{array} \]

Answer 1

The Correct Option is B
