In a chloride ion (Cl^-), the most common oxidation state for chlorine, there are 8 electrons in the outermost energy level. This is because chlorine has 7 valence electrons, and it gains an additional electron to form the chloride ion, giving it a full outer shell with 8 electrons (octet rule).

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.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
The chloride ion has eight valence electrons.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.

In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 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.
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.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
