  1. 3. an expression that defines the number of atoms of each element in one molecule of a compound
  2. 5. type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound
  3. 6. a representation of the valence electrons of an atom that uses dots around the symbol of the element
  4. 9. a covalent linkage in which two atoms share three pairs of electrons
  5. 10. consists of molecules whose formula represents the actual number of atoms bonded together in the molecule
  6. 13. a symbolic representation of its chemical composition.
  7. 16. a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
  8. 17. the energy required to separate an isolated molecule (i.e. in gas phase), after the cleavage of a bond, into two fragments (atoms or radicals) at infinite distance
  9. 18. the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound

  1. 1. when atoms with different electronegativities share electrons in a covalent bond.
  2. 2. a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond.
  3. 4. a chemical bond in which one pair of electrons is shared between two atoms.
  4. 7. a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
  5. 8. a type of chemical bond that is formed when electrons are shared equally between two atoms
  6. 11. the absolute grouping of atoms or ions represented by the empirical formula of a compound, either ionic or covalent.
  7. 12. an ion that contains more than one atom
  8. 14. a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula
  9. 15. a very simplified representation of the valence shell electrons in a molecule
