Question

answer: What is the no. of orbitals in n=3​

Answer 1

The answer is 9 orbitals.

3s has 1 orbital, 3p had 3 orbitals and 3d has 5 orbitals....

Total 9

Answer 2

Answer:

The total no. of orbitals in n=3​ is 9

Explanation:

According to the principle of quantum number, the number of orbitals is equal to n²

Here,

We see that, n = 3 (given)

And the orbital consists:-

3s   ⇒ 1 orbital.

3p  ⇒ 3 orbitals.

3d  ⇒ 5 orbitals.

Now,

For n = 3

number of orbitals = n²

                               = 3²

                               = 9

Hence, number pf orbitals is 9 in n = 3.
