- b The energy released when an atom or ion in the gaseous state gains an electron. Increases from left to right and from bottom to top on the Periodic Table.
- c Results from sharing electrons between two atoms, usually nonmetal atoms.
- d An attractive force between ions of opposite charges, often a metal cation and a nonmetal anion.
- e Form when electrons transfer from an atom of low ionization energy (usually a metal) to an atom of high electron affinity (usually a nonmetal). The electrostatic attraction between two oppositely charged ions constitutes this bond.
5 Multiple choice questions
- The relative ability of an atom to attract a pair of electrons. Increases from left to right and from bottom to top. Fluorine has the highest and francium has the lowest. gas>liquid>solid Determines polarity.
- A quantitative measure of the magnitude of a dipole. The higher the dipole moment, the more polar is the molecule.
- The greater the electronegativity difference between two atoms the more polar the bond.

- MG Tetrahedral
MG Trigonal pyramidal
5 True/False questions
Lattice Energy → (∆ H lattice) is the energy required to completely separate a mole of a solid ionic compound into its gaseous ions. Ionic compounds tend to have high lattice energies, which tend to make ionic compounds hard and brittle with relatively high melting points.
Nonpolar Covalent Bond → A bond in which the electrons are shared equally between two atoms.
Lewis Structure → 1) Total the valence electrons of all bonded atoms. (- means you add electrons, + means you subtract electrons)
2) Use one pair of electrons to bond each outer atom to the central atom.
3) Complete the octets around all of the outer atoms.
4) Place any remaining electrons on the central atom.
5) If there are not enough electrons to give the central atom an octet, make multiple bonds.
Polar Covalent → 0.4-1.0
EDG Linear → MG Linear
