Web15 aug. 2024 · Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a positively charged cation. If a balanced atom gains one or more electrons, it will become a negatively charged anion. What is a cation? WebWhy is it referred to as a cation? A cation (+) (/kta.n/ KAT-eye-n, from the Greek word káto, which means “down”) is an ion that has fewer electrons than protons and has a positive charge. In 1834, Michael Faraday introduced the terms anion and cation (for ions that travel to the anode and cathode respectively during electrolysis).
Web5 mei 2024 · A cation is an ionic species with a positive charge. The word "cation" comes from the Greek word "kato," which means "down."
