Atoms 1.6 understand the differences between elements, compounds and mixtures

Elements, compounds and mixtures

Elements and compounds have their own chemical properties. The properties of a compound are likely to be different from the elements that have been used to make it. A mixture will have the properties of each substance been used to make it.

Elements- Only one substance, all elements are listed on the periodic table. e.g Na, O, Fe

Molecules- 2 or more elements bonded e.g NaCl, MgO

Mixtures- 2 or more elements that have not been bonded together e.g Iron and sulfur
