  • Ion - Wikipedia
    Ions consisting of only a single atom are termed monatomic ions, atomic ions or simple ions, while ions consisting of two or more atoms are termed polyatomic ions or molecular ions If only a + or − is present, it indicates a +1 or −1 charge, as seen in Na + and F − (fluoride ion)
  • Ion | Definition, Chemistry, Examples, Facts | Britannica
    Ion, any atom or group of atoms that bears one or more positive or negative electrical charges Positively charged ions are called cations; negatively charged ions, anions Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells
  • What Is an Ion? Definition and Examples - ThoughtCo
    Ions are atoms or molecules that gain or lose electrons and carry an electrical charge Cations are positively charged ions, while anions are negatively charged ions Ions can be single atoms or groups of atoms forming monatomic or polyatomic ions
  • What Is an Ion? Chemistry Definition - Science Notes and Projects
    In chemical reactions, ions form when atoms or molecules gain or lose valence electrons Only nuclear reactions change the number of protons in a chemical species The two types of ions are anions and cations An anion has a net negative electrical charge It contains more electrons than protons
  • “An ion is a small electrically charged particle. Ions are single . . .
    There are only two types of ions- Cations and anions Cations are positively charged particles or ions and anions are negatively charged particles or ions

  • 3. 5: Ions and Ionic Compounds - Chemistry LibreTexts
    Electrons can move from one atom to another; when they do, species with overall electric charges are formed Such species are called ions Species with overall positive charges are termed cations, while species with overall negative charges are called anions
  • Ion - Simple English Wikipedia, the free encyclopedia
    Making an ion from an atom or molecule is called ionization Two or more ions can combine to make a chemical compound The link between the ions is called an ionic bond The charge on a proton is chosen as +1 (positively charged) The charge on an electron is opposite to the charge on the proton
  • Ion - Definition and Examples - Biology Online Dictionary
