Question

How many orbitals are contained in the third principal level (n = 3) of a given atom?

Answer 1

The third principal level(n=3) of a given atom has 9 orbitals.

what are orbitals?

• orbitals are different energy sub-levels.

• orbitals are of 4 types.

• each orbital has a unique and different shape.
• four types of orbital are-s, p, d, f

The 3rd electron shell has 3 subshells - 3s, 3p, 3d

• s subshell only has one orbital.
• p subshell has three orbitals.
• d subshell has five orbitals.

therefore, the total number of orbitals in the third electron shell is:

1+3+5=9 orbitals
