MIDAY CH 6 Vocabulary

3. a model used to predict 3-D molecular geometry based on the number of valence shell electron bond pairs among the atoms in a molecule or ion.
4. Complete transfer of electrons from metal (cation, giver) to nonmetal (anion, taker).
8. involves atoms combining to form chemical compounds and bring stability to the resulting product.
9. occur when electrons are shared unequally between atoms in the same molecule due to a high difference in the electronegativity of the atoms involved.
10. equal sharing of electrons.
12. a very simplified representation of the valence shell electrons in a molecule.
13. unequal sharing of electrons.
15. sharing of two electrons (one from each atom).
17. a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom with N, O or F.

1. a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
2. Bonds that only occur between "normal" metals like the transition metals.
5. sharing of four electrons (two from each atom).
6. the forces that hold atoms together within a molecule.
7. the tendency of atoms to prefer to have eight electrons in the valence shell.
8. Sharing of electrons in pairs between two nonmetals, which form bond lines.
11. a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula.
14. a covalent bonded compound.
16. an ionic bonded compound.
