Question

How are chlorides made?

Answer 1

By chlorides, I assume you mean -chloride ionic compounds.

Explanation:

`Cl^-` is an anion, where it gains one electron from any source.

This gained electron (highlighted in red) can come from any electron-donating ion.
Let's take the most common chloride salt formed, `NaCl` (sodium chloride).
Sodium as an atom has one electron in its outermost 2s1 sub-orbital, hence the `Na^+` ion easily donates its single valence electron to the `Cl^-` ion, allowing both to gain a stable noble gas electronic configuration.
