The Periodic Table of ElementsWhat is an element? Elements are substances that are made up of only one type of atom (particle). They cannot be broken down into anything simpler.
Electrical Conductors Which elements can conduct electricity?
What is a mixture? What is a compound? 2 Elements A mixture A compound http://www.brainpop.com/science/matterandchemistry/compoundsandmixtures/
Naming compounds The Rules • The names of the elements are written from left to right as they appear on the periodic table e.g. Sodium chloride • If there are only 2 elements forming the compound then the ending of the second name is “ide” e.g. Copper and sulphur is called copper sulphide • If the compound contains oxygen and 2 other elements the ending of the second name is usually “ate” e.g. Copper, sulphur and oxygen is called copper sulphate
What elements make up… magnesium oxide

Signs of a chemical reaction... Precipitate forms (solid/cloudy)
Signs of a chemical reaction... Gas forms (fizzing/bubbling)
Signs of a chemical reaction... Temperature Change (energy released heat/light/sound)

How could we speed up the rate a chemical reaction happens?!
