an f orbital
f orbital corresponds to n=4. l = n-1 = 3. The magnetic quantum numbers run from -l to l, or -3, -2,... 3. Thus there are seven possible magnetic quantum numbers, or seven orbitals. Since each orbital has 2 electrons max, an f orbital can hold 14 electrons.
In a ground-state tellurium atom, there are no electrons in orbitals labeled by l equals 1. l equals 1 corresponds to p orbitals, and tellurium's electron configuration fills up to the 5p orbital. So, there are 0 electrons in orbitals with l equals 1 in a ground-state tellurium atom.
There are four electrons with l=1 (p orbital) in the ground state of chlorine. This is because a chlorine atom has 17 electrons, and the p subshell can hold a maximum of 6 electrons (2 electrons per px, py, and pz orbital).

The (n + l) rule, also known as the Aufbau principle, is a guideline used to determine the order of electron filling in atomic orbitals. It states that electrons occupy orbitals in order of increasing values of the sum of the principal quantum number (n) and the azimuthal quantum number (l). For example, the 3s orbital (n=3, l=0) has a value of 3, while the 4s orbital (n=4, l=0) has a value of 4, so the 3s fills before the 4s. Similarly, the 3p orbital (n=3, l=1) has a value of 4, making it fill after the 4s but before the 3d orbital (n=3, l=2), which has a value of 5.
f orbital corresponds to n=4. l = n-1 = 3. The magnetic quantum numbers run from -l to l, or -3, -2,... 3. Thus there are seven possible magnetic quantum numbers, or seven orbitals. Since each orbital has 2 electrons max, an f orbital can hold 14 electrons.

max. 6 electrons can be accommodated
If n=0 that means there are no values for l
S orbital
There are four electrons with l=1 (p orbital) in the ground state of chlorine. This is because a chlorine atom has 17 electrons, and the p subshell can hold a maximum of 6 electrons (2 electrons per px, py, and pz orbital).

An orbital can have a maximum of two electrons that have different sets of the four quantum numbers (n, l, ml, ms).

The azimuthal quantum number, denoted by l, determines the shape of an orbital and ranges from 0 to n-1 for a given principal quantum number n. For example, when l=0, the orbital is an s orbital, l=1 corresponds to a p orbital, l=2 represents a d orbital, and l=3 signifies an f orbital.
