- parts per million
- vapor pressure
- periodic table
- a A state of matter in which the particles move about freely while the substance retains a definite volume; thus, liquids flow and take the shape of their containers.
- b The distance between consecutive peaks and troughs in a wave.
- c The pressure exerted by a vapor in equilibrium with its liquid.
- d An arrangement of the elements according to their atomic numbers. The table consists of horizontal rows, or periods, and vertical columns, or families, of elements. Each period ends with a noble gas.
- e A measurement of the concentration of dilute solutions now commonly used by chemists in place of mass percent.

- The grams of solute in 100 g of a solution.
- A gas that behaves exactly according to theory.
- A solution containing less solute per unit than its corresponding saturated solution.
- A solution with one mole of solute per mole of solution.
- The mass of a mole of atoms or molecules.
5 True/False questions
salts → A state of matter that has no shape or definite volume.
saturated solution → A solution containing more solute than needed for a saturated solution at a particular temperature.
vapor-pressure curve → The characteristics of substances that give them unique identities.
Thomson model of the atom → Thomson asserted that atoms are not indivisible but are composed of smaller parts; they contain both positively and negatively charged particles- protons as well as electrons.
neutron → A subatomic particle that is electrically neutral and is found in the nucleus of an atom.
