Each element has a chemical symbol. How do we represent chemicals universally?
Some chemical symbols consist of two letters (as there are more than 26 elements). Chemical symbols start with a capital letter. What rules apply to all chemical symbols?
T Compounds have chemical formulae which show the elements in the compound. What does the chemical formulae of a compound show?
W Compounds have chemical formulae with more than one capital letter in. How can you tell a compound from the formula of it?

Demo 1: show different properties of elements Fe and S in a mixture compared to as a compound of FeS.
W Elements have chemical formulae with only one capital letter in. How can you tell an element from the formula of it?
A Students can identify the number of elements in a compound from its formulae. How can we identify the number of elements in a compound?
A Students can identify the number of atoms in a compound from its formulae. Identify the number of element and atoms in the following formulae: CO Co NaOH MgO MgSO4 CaCO3 CaCl What are the elements in the above formulae?
W Mixture 'formulae' have a plus sign in. How can you represent a mixture in writing?
