Question

(6) The number of radial nodes for 3p orbital is
(B) 4​

Answer 1

Answer:

1

Explanation:

The number of radial nodes is related to the principal quantum number, n. In general, a np orbital has (n - 2) radial nodes, so the 3p-orbital has (3 - 2) = 1

Answer 2

Complete Question :

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

A) 3

B) 4

C) 2

D) 1

Answer:

Option D) 1 is the correct answer.

Describe the Radial nodes:

• Nodes are the areas or gaps surrounding the nucleus where there is no chance of encountering an electron.
• The portion of a sphere's surface known as a radial node has a 0% probability of having an electron there.
• It is reliant on the primary quantum number and azimuthal quantum number values.
• As the principal quantum number of orbital rises, so do the number of its nodes.
• The formula can be used to determine radial nodes:
• Radial node count = n-l-1 = n- (l-1)

where l is the azimuthal quantum number and n is the main quantum number.

Solution:

As we know,

Radial node number =  =n−(l−1)    

where the azimuthal quantum number is l and the main quantum number is n.

N=3 and l=1 for the 3p orbital

So,

For the 3p orbital,

the number of radial nodes is 3−1−1

=3−2 =1

Hence, D is the right response.
