Covalent bonding takes place between non-metalandnon metal atoms
Atoms share some of their outer electrons in order to achieve a stable noble gas structure
Small group of Covalently Bonded Atoms is called a Molecule e.g Carbon has 6e in arranged as 1s2 2s2 2p2 Hydrogen has 1e
A) Covalent Bond
In a double bond 4 electrons are shared, 2 atoms in an oxygen molecule share 2 pairs of electrons, configuration 1s2 2s2 2p4
A) Double Covalent Bond
Properties of covalent compounds: Lowmelting and boiling points as there are strong covalent bondsbetweentheatoms within molecules, however there is only a weak attraction between molecules
