Question

Which of the following orbitals has two spherical nodes?

• A. $2s$
• B. $4s$
• C. $3d$
• D. $6f$

Answer 1

The correct option is D $6f$

Number of spherical nodes $=n-l-1$
For $2s$ orbital, the number of spherical nodes $=2-0-1=1$
For $4s$ orbital, the number of spherical nodes $=4-0-1=3$
For $3d$ orbital, the number of spherical nodes $=3-2-1=0$
For $6f$ orbital, the number of spherical nodes $=6-3-1=2$
