Covalent Bonding
Covalent bonding is the bonding between two or more non-metals. This is where a non-metal, often in group 4, will share a pair of electrons in order to complete their outer shells and become a stable compound or element molecule. However, unlike ionic bonding, covalent bonding does not entail any electron transfers; no electrons are lost or given. Rather than transferring the electrons, the element will share a pair of its electrons to complete the outer shell.
Covalent bonding occurs between atoms of the same element (forming a molecule) and atoms of different elements (forming a covalently bonded compound). Elements like hydrogen and oxygen are naturally found with covalent bonds as H2 and O2 as these ae much more stable than just H or O on their own (these do not have full outer shells).
Additionally it's difficult for group 4 elements to gain or lose electrons in ionic bonding as it requires too much energy. This is why group 4 elements frequently bond covalently. Frequently mentioned covalently bonded compounds to note include;
