5 valence 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.
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.
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.
The 3rd energy level is the highest occupied energy level for chlorine with seven 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.
Sr has two electrons in the 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.
Aluminum has 3 electrons in its highest occupied energy level.
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.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
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.
