Homework Ch.2 Question 15, 6th Edition

Postby VGonzalez » Tue Oct 23, 2018 2:10 pm

How many (a) nodal planes, (b) radial nodes are there in a 3p-orbital?

Is there a way to tell how many nodal planes and radial nodes there are based on an electron state?
What exactly are radial nodes?

I think there would be 1 nodal plane in each p orbital. There are 3 orbitals in the p-block, so technically there would be 3 total nodal planes- 1 in each orbital.

I think the more important concept would be that simplest s-orbitals have 0 nodal planes, p-orbitals have 1, d-orbitals have 2, and f-orbitals have three. This is the answer given in the solutions manual.

The number of nodal planes is equal to the value of l. So for 3p, l =1, thus there would only be one nodal plane.

The answer given in the solution manual is
a) 1 nodal plane
b) 2 radial nodes

But the textbook says that

Number of radial nodes
= n-1-l
Which should give us
=3-1-1
=1

Can someone explain why is the answer 2 instead of 1 please?

For b) the number of radial nodes
