Electronegativity

Electronegativity is the ability of an atom to attract electrons in its bond determined by the nuclear charge, number of protons and the number of shells.

Electronegativity of the Elements

Electronegativity is a measure of the ability of an atom to attract electrons towards it in a covalent bond

Bond Strength

Bond strength is the measure of how strong a bond is in terms of the energy needed to make and break the bond

London Dispersion Forces

London dispersion forces are the weakest type of intermolecular forces and require very little energy to overcome them. They are very often found in non polar molecules that are in simple covalent compounds or elements.

Dipole Attraction

Dipole - Dipole forces are usually found between molecules that have a difference in electronegativity so the electrons are unevenly distributed meaning that the molecule is polar. Due to its polarity this means a weak dipole forms which forms a weak intermolecular attraction to the molecule next to it.

Hydrogen Bonding

Hydrogen bonding is the strongest type of intermolecular force that exists between simple covalent compounds and molecules. It exists when the two elements in a covalent bond have a large electronegativity difference such as when hydrogen is bonded to either fluorine, oxygen or nitrogen.
