Ionic Bonding
An electrostatic interaction between oppositely charged ions.
1 of 15
Covalent Bonding
A shared pair of electrons with one electron coming from each atom.
2 of 15
Co-ordinate Bonding
Covalent bonding with both electrons coming from 1 atom.
3 of 15
Electronegativity
The ability of an atom to attract a pair of electrons within a covalent bond.
4 of 15
Dipoles
A difference in charge across a covalent bond.
5 of 15
Permanent Dipoles
Formed due to a difference in electronegativity.
6 of 15
Temporary Dipoles
Formed when electrons spin closer to one atom than the other.
7 of 15
Vander Waals
A very weak electrostatic force of attraction that exists between molecules. The bigger the molecule, the more Vander Waals can exist.
8 of 15
Hydrogen Bond
An electrostatic interaction between molecules that contain hydrogen directly bonded to NOF. Very weak force of attraction. Stronger than Vander Waals.
9 of 15
Lone Pair
A lone pair of valence shell electrons involved in bonding.
10 of 15
Bonding Pairs
A pair of valence shell electrons involved in bonding.
11 of 15
Lone Pair : Lone Pair
Most Repulsion.
12 of 15
Bonding Pair : Bonding Pair
Least Repulsion.
13 of 15
VSEPR
Electron pairs around a central atom will move apart as far as possible in order to minimise repulsion.
14 of 15
Solubility
A measure of the amount that is dissolved in a known volume of solvent.
