Learning path
In the order the concepts build on each other.
- MoleculeLockedA small group of two or more atoms joined together. A water molecule is two hydrogen atoms and one oxygen atom; the oxygen in the air is pairs of oxygen atoms.Opens after: Element
- CompoundLockedA substance made of two or more different elements joined together, like water or table salt. A compound has its own new properties, and unlike a mixture it can't be pulled apart with a sieve, a filter or a magnet.Opens after: Molecule, Chemical reaction
- Chemical formulaLockedA short way of writing which atoms are in a substance and how many of each, like H₂O for water: the symbols say which elements, and the small number after a symbol says how many atoms of it (no number means one).Opens after: Compound, Chemical symbol
