(a)
Interpretation: The number of sublevels in principal energy level 1 needs to be determined.
Concept introduction: An atomic orbital explains the position of an electron in an atom. An atomic orbital can be occupied by a maximum of two electrons with opposite spins. The four basic atomic orbitals are s, p, d, and f . The number of electrons in each orbital can be explained with the help of quantum numbers. There are four quantum numbers; principal quantum number ( n ), azimuthal quantum number ( l ), magnetic quantum number (
(a)
Explanation of Solution
For the given principal quantum number (n), the azimuthal quantum number can be calculated as follows:
Since the principal quantum number is given 1, the value
Thus,
There is only 1 value for an azimuthal quantum number, which is 1.
Thus, there is only 1 subshell in principal energy level 1 that is s subshell.
(b)
Interpretation: The number of sublevels in principal energy level 2 needs to be determined.

(b)
Explanation of Solution
For the given principal quantum number (n), the azimuthal quantum number can be calculated as follows:
Since the principal quantum number is given 2, the value
Thus,
There are two values for an azimuthal quantum number that is 0 and 1.
Thus, there are two subshells in principal energy level 2 that is s and p subshells.
(c)
Interpretation: The number of sublevels in principal energy level 3 needs to be determined.

(c)
Explanation of Solution
For the given principal quantum number (n), the azimuthal quantum number can be calculated as follows:
Since the principal quantum number is given 3, the value
Thus,
There are two values for an azimuthal quantum number that is 0, 1, and 2.
Thus, there are three subshells in principal energy level 3 that is s , p, and d subshell.
(d)
Interpretation: The number of sublevels in principal energy level 4 needs to be determined.

(d)
Explanation of Solution
For the given principal quantum number (n), the azimuthal quantum number can be calculated as follows:
Since the principal quantum number is given 4, the value
Thus,
There are four values for an azimuthal quantum number that is 0, 1, 2, and 3.
Thus, there are four subshells in principal energy level 4 that is s , p , d, and f subshells.
