An anionic species, commonly referred to as an anion, is an ion with a negative electrical charge. It is formed when an atom or group of atoms gains one or more electrons, resulting in an excess of electrons compared to protons. Anions are attracted to positively charged particles and environments. Here are some key points…

A cationic species, commonly referred to as a cation, is an ion with a positive electrical charge. It is formed when an atom or group of atoms loses one or more electrons, resulting in an excess of protons compared to electrons. As a result, cations are attracted to negatively charged particles and environments. Here are…

A polyatomic ion is a charged chemical species consisting of two or more atoms that are covalently bonded and carry an overall electrical charge. Unlike simple ions (monatomic ions), which consist of single atoms with a charge, polyatomic ions are formed when a group of atoms collectively gains or loses electrons, resulting in a net…
