C Acids & BasesAcids and bases are chemical opposites that react together during neutralisation to form a salt and water.C Chemical ReactionsChemical reactions rearrange atoms into new substances with new properties while total mass is conserved.C Rates of Chemical ReactionsReaction rate measures how fast reactants turn into products during a chemical reaction.C Elements, Compounds & MixturesEverything around us is made of matter, which can be sorted into elements, compounds and mixtures depending on whether atoms are chemically joined.C Metals & Non-MetalsElements are grouped as metals or non-metals, and the two groups behave very differently.C Separating MixturesA mixture contains two or more substances mixed together but not chemically combined, so they can be separated using physical methods.C SolutionsA solution is a mixture formed when a solute dissolves completely and evenly into a solvent.C States of MatterMatter is anything that has mass and takes up space, existing as a solid, liquid, or gas.C Structure of the AtomAn atom is the basic building block of all matter, made of a dense central nucleus surrounded by orbiting electrons.C The Periodic TableThe Periodic Table organises all known chemical elements in order of increasing atomic number, placing elements with similar chemical properties into…C Ratio of Atoms in CompoundsChemical compounds contain different elements chemically joined in fixed numerical ratios of atoms, represented by chemical formulae.
