The chloride ion (Cl-) has 8 electrons on the outermost energy level.
A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.
Bromine has 7 electrons in its outermost energy level.
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
Phosphorus has 5 electrons in its outermost principal energy level.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.

The chloride ion has eight valence electrons.
A chloride ion (Cl⁻) has gained one electron compared to a neutral chlorine atom, which originally has seven valence electrons in its outermost energy level. Therefore, as a chloride ion, it has eight electrons in its outermost energy level. This configuration is stable and corresponds to the noble gas configuration of argon.

The chloride ion in table salt has 8 electrons in its outermost energy level. This is because it has gained an extra electron to achieve a full octet of 8 electrons, making it a stable, negatively charged ion.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Aluminum has 3 electrons in its outermost energy level.
valence electrons are the electrons in the outermost energy level
