- 1AtomSmallest element part that can exist. No electrical charge and made up of neutrons, protons and electrons.
- 2ProtonPositively charged particle in the nucleus of an atom.
- 3NeutronParticle with no charge in the nucleus of an atom.
- 4ElectronNegatively charged particle which orbits the nucleus of an atom, also known as energy levels (shells).
- 5Energy Level (Shell)The area around a nucleus that an electron orbits.
- 6Atomic NumberNumber of protons in an atom.
- 7Mass NumberNumber of protons plus the number of neutrons in an atom.
- 8IsotopesAtoms with the same number of protons but a different amount of neutrons.
- 9Relative Atomic MassThe average mass of atoms on an element, depending on mass and amount each isotope contains.
- 10IonAn electrically charged particle, different number of protons to electrons.
- 11ElementA substance which contains only one type of atom, cannot be further simplified by chemical methods.
- 12CompoundSubstance made by different types of elements chemically bonded together.
- 13Noble GasesElements in Group 0 of the periodic table.
- 14Alkali metalsElements in Group 1 of the periodic table.
- 15HalogensElements in Group 7 of the periodic table.
- 16Diatomic moleculeA molecule containing two atoms.
- 17HalidesCompounds made from group 7 elements.
- 18CatalystSubstance that speeds up a chemical reaction but is not used up.
