| Elements are... | Pure substances made of only one type of atom |
| Each element has a | Symbol and is listed on the periodic table |
| Elements can be divided into two broad categories | Metals and nonmetals |
| On the periodic table the groups go and the periods go | The groups go down and the periods go across |
| Physical properties include things like | Melting and boiling points, ductility conductivity hardness magnetism etc |
| Metals are found on the left hand side of the periodic table and have the following properties | Ductile malleable high Melting and boiling points except Mercury shiny sonorous dense conduct heat and electricity 3 metals namely cobalt nickel and iron are magnetic |
| Non-metals are found on the right hand side of the periodic table and have the following properties | Good electrical insulator except graphite good thermal insulators dull low melting and boiling point nonmagnetic generally low density there are exceptions to this rule |
| Metal can react with nonmetals to form | Compounds |
| A compound is when | Two or more different atoms are chemically joined together |
| Metal oxide is when a metal | Reacts with oxygen |
| Metal sulphides is made when a metal | Reacts with sulphur |
