C1.3 Keywords

C115
  1. Covalent bond (2) - C1:2
    • A chemical bond formed between non-metal atoms, which combine together by sharing electrons.
  2. Lattice (2) - C1:2
    • a regular repeated three-dimensional arrangement of atoms, ions, or molecules in a metal or other crystalline solid.
  3. Ion (2) - C1:2
    • an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  4. Metallic bond (2) - C1:2
    • is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.
  5. Electrostatic attraction (2) - C1:2
    • the phenomenon where a negatively charged atom or molecule is attracted to a positively charged atom or molecule
  6. Ionic bond (1) - C1:1
    • A chemical bond formed by the electrostatic attraction of oppositely charged ions. Formed between a metal and non-metal.
  7. Dot cross diagram (1) - C1:1
    • A diagram used to represent the transfer of electrons in a chemical bond.
  8. Molecule (1) - C1:1
    • A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
  9. Ratio (1) - C1:1
    • A ratio is a way to compare amounts of something
  10. Simple molecule (1) - C1:1
    • Simple molecules contain only a few atoms held together by covalent bonds.
  11. Delocalised electrons (1) - C1:1
    • are electrons in a molecule, ion or solid metal that are not associated with a single atom
  12. Giant covalent (1) - C1:1
    • contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular
  13. Ionic compound (1) - C1:1
    • is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding
  14. Ball and stick model (1) - C1:1
    • is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them
  15. Electronic structure (1) - C1:1
    • is the state of motion of electrons in an electrostatic field created by stationary nuclei.
