The highest energy sublevel for tellurium (Te), which has an atomic number of 52, is the 5p sublevel. In its electron configuration, tellurium is represented as [Kr] 5s² 4d¹⁰ 5p⁴, indicating that the 5p sublevel is the outermost and highest energy level occupied by electrons.
The next highest energy atomic sublevel after 4p is the 5s sublevel. In the electron configuration of an atom, energy levels increase with increasing principal quantum number (n), so the 5s sublevel is higher in energy than the 4p sublevel.
One electron occupies the highest energy sublevel of alkali metals. Alkali metals have one electron in their outermost energy level, making them highly reactive.

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).
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 next highest energy atomic sublevel after 4p is the 5s sublevel. In the electron configuration of an atom, energy levels increase with increasing principal quantum number (n), so the 5s sublevel is higher in energy than the 4p sublevel.
One electron occupies the highest energy sublevel of alkali metals. Alkali metals have one electron in their outermost energy level, making them highly reactive.
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.

The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
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).
There are two sublevels in the second principal energy level: the s sublevel and the p sublevel. The s sublevel can hold a maximum of 2 electrons, while the p sublevel can hold a maximum of 6 electrons.
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.
Actinium is in period 7, group 3A : so 7s2 is the highest sublevel of this first 5f-block element the actinides (89-103).
It is the f sublevel. Uranium has the configuration [Rn] 5f3 6d1 7s2.
The s sublevel in the third main energy level is indicated by 3s.
