- 1AtomsA particle made up of protons, neutrons and electrons with no overall electric charge
- 2ElementA substance containing only one type of atom
- 3CompoundsA substance that contains two or more elements chemically joined together to form a new substance with new properties
- 4ElectronsA tiny particle that occupies an energy level around an atoms nucleus. Responsible for the chemical bonds between atoms, and move through metals when a current flows
- 5NucleusThe central part of an atom containing most of the mass
- 6Energy levelsA position that electrons can occupy around an atom, aka an electron shell
- 7Electron shellsA position that electrons can occupy around an atom aka energy level
- 8ProtonA subatomic particle found within the atomic nucleus, with a single positive charge and a relative mass of 1
- 9Group 1Alkali metals
- 10Group 7Halogens
- 11LatticeA regular, continuous structure of atoms or ions e.g. crystal
- 12Ionic bondA chemical bond in which oppositely charged ions are held together by mutual attraction
- 13ionic compoundAn ionically bonded compound
- 14Giant covalent structuresA structure containing billions of atoms in a network linked together by covalent bonds
- 15FertilizerA compound added to soil to replace the minerals used up by plants
- 16Hydrogen ionA hydrogen atom without its electron; a proton, acids release hydrogen ions when they dissolve in water
- 17Metallic structureA giant structure of close-packed, positively charged metal ions surrounded by delocalised electrons
- 18DelocalisedElectrons that have dissociated from their individual atoms
- 19MRIImaging technique, usueful for visualising the soft tissues of the body
- 20Large hadron colliderLargest particle accelerator. Smashed together in high-energy collisions to give physicists information about the structure of matter
