heat : the form of energy associated with the motion of small particles of matter.
density : mass per unit of volume.
matter : anything that has mass and occupies space.
atom : smallest unit of an element having the properties of that element.
element : contain only one kind of atom.
compound : a pure substance which may be broken down or decomposed by chemical means.
molecule : contains two or more atoms chemically joined together.
solutions : are homogeneous mixtures which have variable compositions.
mixture : when two or more substances contained physically.
crystalline : forms a three-dimensional structure in which properties are arranged in a repeating pattern.
ions : positively or negatively charged atoms or group of atoms.
period : the horizontal row in the periodic table.
group : the vertical column of elements.
metals : elements with three or less electrons in the outer energy level.
metalloid : a chemical element with properties intermediate between typical metals and nonmetals.
hydrogen : an element which doesn't fit into the division of metals and non-metals.
reactant : the substance entering the reaction.
product : the substance formed in reaction.
solvent : a substance which dissolves another.
solute : a substance which is dissolved.
volatile : refers to a substance that vaporizes readily.
safety : the key concern in any scientific enterprise, but particularly so in the chemistry lab.
molality : the number of moles of solute dissolved in one kilogram of solvent.
molarity : the number of moles of a solute dissolved in a liter of solution.
valence : the number of bonds a given atom has formed, or can form, with one or more other atoms.
