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 number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
The highest occupied energy level of Beryllium is the second energy level, denoted as 2.
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.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth 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.
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
