Question

A $3p$ orbital has:

• A. Two spherical nodes
• B. Two non-spherical nodes
• C. One spherical and one non-spherical node
• D. One spherical and two non- spherical node

Answer 1

The correct option is C One spherical and one non-spherical node

Total node $=n-1$
Number of spherical node $=n-l-1$
Number of non-spherical node $=l$
For $3p$ subshell, $n=3$ and $l=1$
$\therefore$ The number of spherical node $=n-l-1=3-1-1=1$
and the number of non-spherical node $=l=1$.
