If we look at the anion meaning, it is an iconic species which possesses a negative charge. If we compare cation versus anion size, the anion is larger because they have extra electrons around them. Sometimes atoms need to gain an electron to make themselves stable. This gaining electron is the reason behind its negative charge. Word “Anion” is basically a Greek word which means “Going Up”. This term was also developed by Faraday and then protons. This is because the atom gains electrons from another atom to get stable. Anions are present in nature in many different ways. Most negative ions are naturally found in places like mountains, beaches, and near waterfalls. Because the evaporation of water can produce negative ions leaving behind a positive charge in water. These naturally occurring anions are also known as “Longevity elements”, as these are able to absorb micro particles in the air and remove bacteria and dust.
