Question

The number of radial nodes for 3p orbital is .................

°3

°4

°2

°1

Answer 1

For determining the radial nodes, we have formula....

n-l-1

here,
n is principal quantum number
l is azimuthal quantum number


For 3p, the no. of radial nodes will be
3-1-1 = 1

( As for 3p, n=3 and l =1 )

Hope you get your answer.
