A covalent bond is one of three forms of intramolecular forces (covalent, ionic and metallic), and is the strongest type of bonding. This type of bond is formed via the sharing of a pair of electrons on adjacent atoms. Depending on the atoms in which the force acts between, the energy required to break a covalent bond differs. This is due to electronegativity; the more similar the electronegativity of two atoms the stronger the covalent bond. More than one electron pair can be shared to form multiple covalent bonds, for example a double bond or triple bond [1].
Atoms can react together, this allows them to form sometimes very large an complex structures. In order for them to form these large molecuels they must form inter molecular forces or bonds which are strong and stable. A covalent bond occurs between atoms in a concept of "elctron sharing". this involves an atom sharing, or donating, one of it's electrons to another atom. This is formed using a covalent bond, the molecuel is formed due to the overlap of the 1s orbital, as each atom only has one electron to donate they are effectively sharing two electrons at the same time, it is this bonding of molecular orbitals that creates a covalent bond [2].
