  • 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 . . .
    Ions are single charged atoms (simple ions) or small charged “molecules” (polyatomic ions) ” Simple ions include Na +, Ca 2+, and Cl – Polyatomic ions include (NH 4) +, (CO 3) 2-, and OH – Unlike protons and neutrons, electrons can be easily removed and added to an atom
  • 3. 3: Types of ions - Chemistry LibreTexts
    During the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions (Figure 3 3 1 3 3 1) Figure 3 3 1 3 3 1: (a) A sodium atom (Na) has equal numbers of protons and electrons (11) and is uncharged
  • What is an ion? - ChemTalk
    Read this tutorial to learn about what an ion is, the differently charged ions, and how they are involved in different branches of chemistry!
  • Ion - Simple English Wikipedia, the free encyclopedia
    Ions are charged because they have an unequal number of protons and electrons Making an ion from an atom or molecule is called ionization Two or more ions can combine to make a chemical compound
  • Ion - Definition and Examples - Biology Online Dictionary
    Ion definition chemistry (ion meaning): An ion is a charge-carrying atom or a charge-carrying molecule An ion’s net charge is never zero since it possesses an unequal number of electrons and protons If the number of electrons and protons are balanced or equalized, the ion changes its state to a stable atom or molecule
  • Definition of ion - Chemistry Dictionary
    Ions form when doing so minimizes the total potential energy of the chemical species involved in the chemical reaction Often, this is achieved by allowing atoms of different elements to achieve a full shell of electrons
  • Ions Explained: Definition, Examples, Practice Video Lessons - Pearson
    Ions are atoms or molecules that carry an electric charge This charge results from the loss or gain of electrons, which are negatively charged subatomic particles When an atom loses one or more electrons, it becomes a positively charged ion, known as a cation
