Question

How many radial nodes are present in 5f orbital?

Answer 1

Radial nodes are the spherical surface region where the probability of finding an electron is zero.

To find out the number of radial nodes in an orbital a formula is used i.e, no. of radial nodes = $n-l-1$.

( where n = principal quantum number, l = azimuthal quantum number).

Here, $n=5\&l=3$. Therefore, the number of nodes$=5-3-1=1$.

Hence, $1$radial nodes are present in $5f$ orbital.
