Mar 3, 2020 · The chemical formula of a compound is always written with the cation first, followed by the anion. For example, Na is the cation and Cl is the anion in NaCl (table salt).

Summary Cations are formed by the loss of one or two electrons from an element. Groups 1 and 2 elements form cations. Cations are named according to the pare nt element. Cation charges are …

A cation is an ion that has lost one or more electrons, giving a net positive charge. Because one or more electrons are removed to form a cation, the cation of an atom is smaller than the neutral atom.

The meaning of CATION is the ion in an electrolyzed solution that migrates to the cathode; broadly : a positively charged ion.

Jan 1, 2026 · Cations Sodium loses an electron to become a cation. Some elements lose one or more electrons in forming ions. These ions are known as “ cations ” because they are positively charged …

Aug 3, 2024 · When writing the formula of a compound, the cation is listed before the anion. For example, in NaCl, the sodium atom acts as the cation, while the chlorine atom acts as the anion.

The opposite of a cation is an anion, which has a negative charge. Cations can have only one atom (monatomic cations) or be made of multiple atoms together (polyatomic cations).

CATION definition: 1. in chemistry, an ion (= type of atom) that has a positive electric charge and therefore moves…. Learn more.

A cation is a positively charged ion that results from the loss of one or more electrons by an atom or molecule. Cations are an essential concept in understanding chemical nomenclature and the periodic …

An anion is an ion that is negatively charged, and is attracted to the anode (positive electrode) in electrolysis. A cation has a net positive charge, and is attracted to the cathode (negative electrode) …
