The chloride ion (Cl-) has 8 electrons on the outermost energy level.
There are 8 electrons in the outermost energy level of a chloride ion (Cl-) in table salt. This is because chlorine has 7 electrons in its neutral state, and when it gains an electron to become Cl-, it has a full outer shell with 8 electrons.
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.
Phosphorus has 5 electrons in its outermost principal 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.

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
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.
Aluminum has 3 electrons in its outermost energy level.
valence electrons are the electrons in the outermost energy level
Halogens have six valence electrons in the outermost energy level.
There are 8 electrons in the outermost energy level of a chloride ion (Cl-) in table salt. This is because chlorine has 7 electrons in its neutral state, and when it gains an electron to become Cl-, it has a full outer shell with 8 electrons.
