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.
