Question

Compare the characteristics of 4d orbitals and 3d orbitals and compared the following sentences. Check all that apply

Answer 1

Answer :

(b) 4d orbitals would be larger in size than 3d orbitals

(e) 4d orbitals would have more nodes than 3d orbitals

Explanation :

As we move away from one orbital to another, the distance between nucleus and orbital increases. So, 4d orbitals would be far to the nucleus than 3d orbitals.

Hence, 4d orbitals would be larger in size than 3d orbitals.

Number of nodes is any orbital is n - 1 where, n is principal quantum number.

So, number of orbital in 4d is 3.

And number of orbital in 3d is 2.

So, options (b) and (e) are correct.
