Definition
The energy given off when one mole of ions of an ionic compound form the crystal lattice.
This is also the amount of energy it takes to break one mole of bonds in a crystal lattice.
One mole of atoms is 6.022 x 1023 atoms. |

Term
|
Definition
| Having the same electron configuration as another atom or ion. Usually this is discussed when an atom becomes an ion and achieves the electron configuration of a noble gas. |
|
|
Term
|
Definition
| Having an equal number of positive and negative charges; therefore the compound is neutral. |
