atom : the smallest basic unit of matter
element : substance made of only one kind of atom
atomic number : number of protons of an element
atomic mass : mass of an atom (protons + neutrons)
isotope : form of an element that has the same number of protons but a different number of neutrons as another element
radioactive isotope: an isotope having an unstable nucleus that decomposes spontaneously by emission of radiation
compound : a substance made of atoms of different elements bonded together in a certain ratio
ion : atom with a charge from gaining or losing electrons
ionic bond : forms through the electrical force between oppositely charged ions.
covalent bond : forms when atoms share a pair of electrons
molecule : two or more atoms held together by covalent bonds
compound : a substance made of atoms of different elements bonded together in a certain ratio
mixture : two or more substances which have been combined such that each substance retains its own chemical identity
solution : a mixture of substances that is the same throughout
solvent : the substance that is present in the greater amount and that dissolves another substance
solute : a substance that dissolves in a solvent
concentration : the measure of the amount of a sub-component (usually the solute) in a solution
pH scale : measures a solution's acidity
acids : compounds that release a hydrogen ion, H+, when dissolved in water
bases : compounds that remove H+ ions from a solution
buffers : substances that neutralize acidic or basic substances
potential energy : energy which an object has because of its position
