Structure and bonding chemistry a level
WebThere are 4 main chemical bonds: ionic, covalent, polar and hydrogen bond. Electronegativity is the property of an atom to attract a shared pair of electrons (or electron density) towards itself. An ionic bond involves a transfer of an electron between two atoms A covalent bond involves the sharing of electrons between two atoms. WebA/AS level. WJEC Chemistry.

Theories of bonding explain how atoms or ions are held together in these structures.
WebA bond in which two atoms share a pair of electrons, both of which are donated by one atom. Behaves the same way as a covalent bond once formed. E.g. Al2Cl6 (lone pair on chlorine is donated to empty orbital on aluminium) and NH4+ (ammonia molecule shares its lone pair with a hydrogen ion H+) WebSimple molecular structures have a low melting and boiling points. Weak intermolecular forces of attraction act between molecules. Small amount of energy needed to disrupt these forces, This...
