Question

The number of radial nodes for 3p orbital is ______.

• A. 3
• B. 4
• C. 2
• D. 1

Answer 1

The correct option is D 1

Number of radial nodes = $=n-l-1$

where n=principal quantum number, l=azimuthal quantum number

For 3p orbital $n=3$ and $l=1$

$\therefore$ Number of radial nodes for 3p orbital $=3-1-1=3-2=1$

So, the correct answer is $D$
