  • Ion - Wikipedia
    Electron transfer from a neutral lithium (Li) atom on the left to a neutral fluorine (F) atom on the right would give a Li + and F − ions An ion ( ˈaɪ ɒn, - ən ) [1] is an atom or molecule with a net electrical charge
  • 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? 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
  • Ions - Atoms, isotopes and ions - AQA - GCSE Combined Science . . . - BBC
    Learn about and revise the structure of atoms, atoms and isotopes and ions with GCSE Bitesize Combined Science
  • 3. 5: Ions and Ionic Compounds - Chemistry LibreTexts
    Learn the characteristic charges that ions have Construct a proper formula for an ionic compound Generate a proper name for an ionic compound So far, we have discussed elements and compounds that are electrically neutral
  • Ion - Simple English Wikipedia, the free encyclopedia
    Ionizing the atom breaks it into two parts: (1) a positively charged hydrogen ion, H+ (2) and a negatively charged electron A liquid with ions is called an electrolyte A gas with lots of ions is called a plasma When ions move, it is called electricity For example, in a wire, the metal ions do not move, but the electrons move as electricity
  • 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
  • Atoms vs. Ions - Division of Chemical Education, Purdue University
    By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion When an ion is formed, the number of protons does not change
  • 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
