  • Cations and Anions: Definitions, Examples, and Differences
    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)
  • Ion - Wikipedia
    A cation is something that moves down (Greek: κάτω, kato, meaning "down") and an anion is something that moves up (Greek: ἄνω, ano, meaning "up") They are so called because ions move toward the electrode of opposite charge
  • CATION Definition Meaning - Merriam-Webster
    The meaning of CATION is the ion in an electrolyzed solution that migrates to the cathode; broadly : a positively charged ion
  • Cation vs Anion: Definition, Chart and the Periodic Table
    What is a cation? A cation has more protons than electrons, consequently giving it a net positive charge For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them
  • 7. 3: Cations - Chemistry LibreTexts
    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 parent element Cation charges are indicated with a superscript following the chemical symbol
  • Cation - Properties, Symbols and Formation | CK-12 Foundation
    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 and migrate toward the negative electrode (cathode) in an electrical field
  • Cations and Anions - Ions | ChemTalk
    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
  • 5. 1 Ionic Bonding – Chemistry Fundamentals
    A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell
  • The Ionic Bond – Introductory Chemistry
    Cations and Anions Ionic bonds involve a cation and an anion The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation Another atom, typically a non-metal, is able to acquire the electron (s) to become a negative ion, or anion
  • Cation Definition - Intro to Chemistry Key Term | Fiveable
    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 variations in element properties
