Question

The nodes present in $5p$-orbital are:

• A. one planar, five spherical
• B. one planar, four spherical
• C. one planar, three spherical
• D. four spherical

Answer 1

Answer: (C)

one planar, three spherical

For $5p$ orbital $n=5,l=1$

Total number of nucleus $n-1=5-1=4$

angular nodes $=l=1\Rightarrow$one planar node

radial nodes$=4-1=3$

Number of spherical nodes in an orbital is equal to $n-l-1=5-1-1=3$
Option C is correct.
