|
|
Crystal lattice
|
a three - dimensional geometric arrangement of particles in which each positive in is surrounded by negative ions and each negative ion is surrounded by positive ions
|
|
|
Ionic bond
|
The electrostatic force that holds oppositely charged particles together in an ionic compound.
|
|
|
Ionic compuond
|
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 and is also affected by the charge of the ions.

The positive or negative charge of a monotonic ion.
|
|
|
Polyatomic ion
|
an ion made up of two or more atoms bonded together that acts as a single unit with a net charge
|
|
|
Covalent bond
|
a chemical bond that results from the sharing of valence electrons.
|
|
|
Lewis structure
|
A model that uses electron - dot structures to show how electrons are arranged in molecules. pairs of dots or lines represent bonding pairs.
|
|
|
Molecule
|
forms when two or more atoms covalently and is lower in potential energy that its constituent atoms
|
|
|
Structural formula
|
a molecular model that uses symbols and bonds to show relative positions of atoms;
|
|
|
Polar covalent bond
|
a type of bond that forms when electrons are not shared equally.
