|
Anion |
An ion that has a negative charge. |
|
|
Cation |
An ion that has a positive charge |
|
|
Chemical Bond |
The force that holds two atoms together; May form by the attraction of a positive ion for a negative ion or by sharing electrons |
|
|
Covalent Bond |
A chemical bond that results from the sharing of valencr electrons |
|
|
Crystal Lattice |
A 3- dimensional geometric arrangement of particles in which each positice ion is surrounded by a negative ions & each negative is surrounded by positive ions; Vary in shape due to size & relative numbers of the ions bonded |
|
|
Formula Unit |
The simplest ratio of ions represented in an ionic compound |
|
|
Ionic Bond |
The electrostatic force that holds oppositely charged particles together in an ionic compound |
|
|
Ionic Compounds |
Compounds that contain ionic bonds |
|
|
Lattice Energy |
The energy required to separate one mole of the ions of an ionic compound, which is directly related to the size of the ions bonded & is also affected by the charge of the ions |
|
|
Lewis Structure |
A model that uses electron dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pair |
|
|
Molecule |
Forms when 2 or more atoms covalently bond & is lower in potential energy tham its constituent atoms |
|
|
Oxidantion Number |
The positive or negative charge of a monatomic ion |
|
|
Polar Covalent Bond |
A type of bond that forms when electrons are not shared equally |
|
|
Polyatomic Ion |
An ion made up of 2 or more atoms bonded together that acts as a single unit with a net charge |
|
|
Structural Formula |
A molecular model that uses symbols & bonds to show relative positions of atoms; Can be predicted for many molecules by drawing the Lewis Structure |
