The number of radial node/s for 3 p orbital is:

Options

  1. A1
  2. B4
  3. C2
  4. D3

Correct answer

A. 1

Step-by-step solution

A point or plane of an orbital where the electron density of the electron of an orbital is zero is called a node. Nodes can be two types; one is a radial node and another one is an angular node. Number of radial node = n - l - 1 Now, for 3 p orbital, the value of n is 3 , and the azimuthal quantum number is 1 . Therefore, the number of radial node is, n - l - 1 = ( 3 - 1 - 1 ) = 1 Hence, ans will be A
