  1. Ion
    • A positively or negatively charged atom or molecule
    • This happens when the atom or molecule loses or gains electrons so that the number of protons and electrons is not even. If the atom has more electrons itÂ’s a negative atom and vice-versa.
  2. Chemical bond
    • A chemical link between two atoms, which holds the atoms together.
    • Some examples are: ionic bond, covalent bond, metallic bond, etc.
  3. Ionic bond
    • A chemical bond that forms between oppositely charged ions.
    • These form between metals and non-metals since metals want to lose electrons and non-metals want to gain electrons.
  4. Ionic compound
    • A compound made of oppositely charged ions.
    • Some examples are: sodium chloride (NaCl), lithium fluoride (LiF), beryllium sulfide (BeS), etc.
  5. Molecular compound
    • A compound formed when atoms of two or more different elements share electrons.
    • Some examples are: carbon tetrafluoride (CF4), oxygen (O2), water (H2O), etc.
  6. Covalent bond
    • A chemical bond in which one or more pairs of electrons are shared by two atoms.
    • These bonds form between non-metals and other non-metals.
  7. Molecule
    The smallest discrete particle of a pure substance, which has one or more shared pairs of electrons.
