|
structural formula |
shows how atoms are bonded in a molecule. |
|
|
bond energy |
is a measure of the amount of energyneeded to break apart one mole of covalently bonded gases. |
|
|
chemical bond |
A mutual attraction between nuclei and valence electrons that binds the atoms together. |
|
|
Lewis structure |
are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. |
|
|
ionic bond |
electrical attraction between cation and anions |
|
|
molecule |
A neutral group of atoms held together by covalent bonds |
|
|
lattice energy |
energy realesed when a crystal lattice forms |
|
|
Vsepr Theory |
States that repulsion between the sets of valence level electrons surrounding an atom causes these sets to be oriented as far apart as possible. |
|
|
formula unit |
A formula unit in chemistry is the empirical formula of any ionic or covalent network solid compound used as an independent entity for stoichiometric calculations. It is the lowest whole number ratio of ions represented in an ionic compound. |
|
|
polar-covalent bond |
The greater the electronegativity difference, the more ionic the bond is. |
