Question

How Many Nodes Are In The$4\mathrm{f}$ orbitals ?

Answer 1

The number of nodes in $4\mathrm{f}$ orbitals:

1. There are seven orbitals in $4\mathrm{f}$ orbitals. These orbitals consist of nodes as well as antinodes. The node have zero possibility of finding electron but antinodes has highest probability of electrons in an orbital.
2. The number of nodes are related to quantum number where Azimuthal quantum number is equal to angular node. For $4f$, $\mathrm{l}=3$.
3. The radial node is equal to$\text{n - l - 1}$. so, $4-3-1=0$.
4. The total nodes will be the sum of angular node and radial node i.e. $\mathrm{N}=3+0=3$.

Thus, Three nodes are present in $4f$orbitals.
