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).

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 …

A cation is a type of ion that has a positive electric charge. [1] This means it has fewer electrons than protons. The opposite of a cation is an anion, which has a negative charge. Cations can …

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

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 …

Dec 1, 2025 · 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 …

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

A cation is an atom or a molecule which is positively charged, i.e. has more number of protons than electrons. Anion originated from the Greek word ano, meaning ‘up’. The word cation …

Roman numeral notation indicates charge of ion when element commonly forms more than one ion. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge.
