The number of radial nodes of \(3 \mathrm{~s}\) and \(2 p\) orbitals respectively are
- A 0,2
- B 2,0
- C 1,2
- D 2,1
Answer & Solution
Correct Answer
(B) 2,0
Step-by-step Solution
Detailed explanation
Number of spherical/radial nodes in any orbital \[ =n-I-1 \] For \(s=\) orbitals, \(I=0\). \(\therefore\) Number of radial nodes in 3s-orbital \[ =3-0-1=2 \] For \(p\) - orbitals, \(I=1\) \(\therefore \quad\) Number of radial nodes in \(2 p\)-orbitals \[ =2-1-1=0 \]
