Question

A 3p-orbital has ?

a) 2 non-spherical nodes
b) 2 spherical nodes
c) 1 spherical and 1 non-spherical node
d) 1 spherical and 2 non-spherical nodes​

Answer 1

Option c) is the right answer

No of spherical nodes = n - l - 1

For 3p, n = 3, l = 1

Spherical nodes = 3 - 1 - 1 = 1

No of non spherical nodes = l

As l = 1 for 3p, non spherical node = 1

Hence 3p has 1 spherical and 1 non spherical node.

Answer 2

Answer:

Spherical node= n-1-1 = 3-1-1=1

ltbRgt Non-spherical node= l-1 =3-1=2

hence,

ans- c) 1 spherical and 1 non-spherical node
