Aluminum has 3 electrons in its highest occupied energy level.
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
8
The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.
7 electrons
The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
2s
The highest occupied energy level for chlorine is the 3rd energy level. This means that the valence electrons of a chlorine atom are in the 3rd energy level.
Sr has two electrons in the highest occupied energy level
Aluminum has 3 electrons in its highest occupied energy level.
Phosphorus has 5 electrons in its highest occupied energy level.
Xenon has a total of 54 electrons. The highest occupied energy level of xenon is the 5th energy level, which can hold a maximum of 18 electrons. Therefore, on the highest occupied energy level of xenon, there are 18 electrons.

7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
the period number tells which is the highest energy level occupied by the electrons
