| Carbon | C |
| Cobalt | Co |
| Iron | Fe |
| Gold | Au |
| Copper | Cu |
| Magnesium | Mg |
| Nitrogen | N |
| Sulfur | S |
| Calcium | Ca |
| Chlorine | Cl |
| Element | Contains only one type of atom e.g. Hydrogen, Oxygen, Carbon, Chlorine Only one capital letter should be present |
| Compound | Contains more than one type of element e.g. sodium chloride, hydrogen peroxide |
| Mixture | Having more than one substance present however, they do NOT mix e.g. sand and salt |
| dio- ... e.g. carbon DIOxide | 2 atoms (in this case 2 oxygen atoms combined with 1 carbon atom) |
| Mono- ... e.g. carbon monoxide | 1 atom (in this case there is only 1 oxygen atom combined with the carbon atom) |
| Atom | Atoms are the building blocks of molecules. They are smaller than molecules e.g. H2 (2 should be subscript): 2 atoms |
| Molecule | one group of element or compound bonded together E.g. 3H2 (2 should be subscript) 3 molecules 6 atoms |
| Periodic table | A table of all the elements. There are a lot of elements (118 elements). They are all written in symbols |
| Metals | conduct electricity conduct heat can be bent shiny when polished all are solids except for mercury Example: cobalt, iron, gold,copper, magnesium, calcium |
| Non-Metals | do not conduct electricity do not conduct heat cannot be bent (brittle) are not shiny can be solids, liquids and gases Example:Hydrogen, oxygen, carbon, nitrogen, sulfur, chlorine |
