valence electrons are the electrons in the outermost energy level
Helium only needs two electrons to have a filled outermost energy level.
Electrons in the outermost energy level are called valence electrons. The number of valence electrons on an atom largely determine its behavior and characteristics.
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
The chloride ion (Cl-) has 8 electrons on the outermost energy level.

The chloride ion has eight valence 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.
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
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.
