Question

Orbital with the highest number of total nodes is:

• A. $5s$
• B. $5p$
• C. $5d$
• D. All of the above have same number of nodes

Answer 1

The correct option is D All of the above have same number of nodes

Total number of nodes = $n-1$, where 'n' is Principal quantum number. Total number of nodes depends only on the Principal quantum number.
So, $5s,5p\text{and}5d$ all have $4$ nodes.
