matter - anything that takes up volume and has mass, atom - the basic unit of matter, pure substance - something made up of only one type of particle, element - a pure substance containing only type of atom, monatomic - contains one atom, not bonded to anything else, neon - a gaseous element that is often used in coloured lights, bonds - the force of attraction that holds atoms together, molecule - a group of 2 or more atoms bonded together, diatomic - contains 2 atoms, bonded together, triatomic - contains 3 atoms, bonded together, lattice - many atoms bonded together in a 3D framework, mixture - something made up of more than one type of particle, not chemically bonded, atomic weight - the average weight of an element, properties - characteristics that can be measured/observed, periodic table - a table of the chemical elements , atomic number - the number assigned to an element in the current periodic table, compound - substance that contains 2 or more different elements chemically bonded together in fixed proportions, chemical formula - symbols used to determine the number and type of atoms in a compound, chemical symbols - 1 or 2 letters that represent chemical letters. e.g He, subscript - a number after an element symbol; how many of those atoms present in a substance, coefficiant - the number before a chemical formula; how many 'lots' of a substance, products - the substances formed during the reaction , reactants - the substances at the beginning of a reaction, law of conservation of mass - total mass of matter doesn't change in a chemical reaction; atoms are rearranged, not created/destroyed, valence electrons - outer shell electrons, energy - the ability to do work/make physical changes to our world, indivisible - cannot be divided into smaller parts, nucleus - the core of an atom, made up of protons and neutrons, neutron (subatomic particle) - particle of 0 charge located inside the nucleus, electron (subatomic particle) - negatively charged particle orbiting the nucleus, proton (subatomic particle) - positively charged particle located inside the nucleus, mass number - a sum of the number of neutrons and protons in an element, energy levels (shell) - distances from the nucleus where electrons can be found, sometimes called shell, electron configuration - the arrangement of electrons in each level around a nucleus, octet - atoms tend to prefer 8 electrons in the outer shell, anion - negatively charged ion, ion - an atom that has positive/negative charge, cation - positively charged ion, homogenous - a substance or mixture has uniform composition and properties throughout.,
