Definition
Transfer of electrons, electrostatic attraction between ions between metals and nonmetals.
Formed by the electrostatic attraction of oppositely charged ions after electron transfer.
The larger the difference in electron affinity between the 2 bonding atims, the more like an ionic (polar) bond will be formed.

|
Definition
| Requires a certain amount of Ionization Energy (kJ/mol) to remove electrons. When an atom gains an electron a certain amount of energy, known as the Electron Affinity, is released. |

Definition
| Gases consist of large numbers of molecules that are in continuous, random motion. The combined vvolume of all the molecules of the gas is negligible relative to the total volume in which the gas is contained. Attractive and repulsive forces between gas molecules are assumed to be negligible. Energy can be transferred between molecules during collisions, but the averagy Kinetic Energy doesn't change as long the the temperature of the gas remains constant. The average Kinetic Energy is proportional to the absolute temperature |
