Chloride
Definition
Chloride is an ion that carries a negative charge (anion) and is formed when the element chlorine gains an electron.
Analogy
Think of chloride like a magnet. Just as magnets have a negative pole, chloride has a negative charge. And just like magnets attract positive poles, chloride attracts positively charged ions in chemical reactions.
