The s sublevel in the third main energy level is indicated by 3s.
The second principle energy level (n=2) does not have an F sublevel. The F sublevel belongs to the third principle energy level (n=3) and higher energy levels.
The third principal energy level contains s, p, and d sublevels, each with different energy levels. The s sublevel has 1 orbital, the p sublevel has 3 orbitals, and the d sublevel has 5 orbitals, all with increasing energy levels.
Electrons occupy orbitals in a definite sequence, filling orbitals with lower energies first. Generally, orbitals in a lower energy level have lower energies than those in a higher energy level. But, in the third level the energy ranges of the principal energy levels begin to overlap. As a result, the 4s sublevel is lower in energy than the 3d sublevel, so it fills first.
Elements with five electrons in the highest energy p sublevel in their ground state are referred to as Group 15 elements. The p sublevel is the third energy level, and these elements are known as the nitrogen group. Examples include nitrogen (N) and phosphorus (P).
You would have to determine the electron configuration for atoms of a given element. Each s sublevel contains 1 orbital, each p sublevel contains 3 orbitals, each d sublevel contain 5 orbitals, and each f sublevel contains 7 orbitals.

The lowest energy level that contains d orbitals is the third energy level. Within the third energy level, starting with the 3d sublevel, the d orbitals become available.

The third principal energy level contains s, p, and d sublevels, each with different energy levels. The s sublevel has 1 orbital, the p sublevel has 3 orbitals, and the d sublevel has 5 orbitals, all with increasing energy levels.
Phosphorus typically fills its outermost electron shell in the third energy level, or s sublevel, in its ground state configuration.
Electrons occupy orbitals in a definite sequence, filling orbitals with lower energies first. Generally, orbitals in a lower energy level have lower energies than those in a higher energy level. But, in the third level the energy ranges of the principal energy levels begin to overlap. As a result, the 4s sublevel is lower in energy than the 3d sublevel, so it fills first.
In the ground state, the outermost principle energy level of an argon atom is the third energy level. This energy level contains the 3s and 3p sublevels. The 3s sublevel can hold up to 2 electrons, while the 3p sublevel can hold up to 6 electrons.
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
The maximum number of electrons that can occupy the third energy level is 18. This level has 2 sublevels, s and p, which can hold a total of 18 electrons. The s sublevel can hold 2 electrons, and the p sublevel can hold 6 electrons, so the total is 2 + 6 + 10 = 18 electrons.
Elements with five electrons in the highest energy p sublevel in their ground state are referred to as Group 15 elements. The p sublevel is the third energy level, and these elements are known as the nitrogen group. Examples include nitrogen (N) and phosphorus (P).
In the element krypton, the third energy level has 3 sublevels: s, p, and d. The s and p sublevels are filled first before the d sublevel. This means that in krypton, the 4s and 4p sublevels are filled, while the 4d sublevel remains empty.
The lowest numbered energy level where a d sublevel is found is the third energy level. Energy levels are represented by numbers (1, 2, 3, etc.) and each level can contain sublevels corresponding to different types of orbitals (s, p, d, f).
