Description

At the end of this activity, students should be able to:
– discuss the formation of covalent bonds
– indicate which elements form covalent bonds
– explain the terms: Lewis dot-and-cross diagrams, structural formula and molecular formula
– name the non-metals that occur in nature in the form of diatomic molecules
– illustrate simple diatomic molecules using molecular formulae, structural formulae and Lewis diagrams
– explain how multiple bonds are formed.

Compounds are substances in which atoms of two, or more, elements are not just mixed together but chemically combined. Chemical bonding involves either transferring or sharing electrons in the highest occupied energy levels (shells) of atoms. When atoms share pairs of electrons, they form covalent bonds (strong). Some covalently bonded substances consist of simple molecules such as H2, Cl2, O2, HCl, H2O and CH4. Others have giant covalent structures, such as diamond and silicon dioxide.
