pairs of electrons
2. A range of values used to express the acidity or
alkalinity of a substance
3. Any compound that releases hydrogen ions
(hydronium ions) in solution

reaction
7. The force that holds molecules of a single material
together (water being attracted to another molecule
of water)
8. The bond formed when a slightly positive
hydrogen atom is attracted to a slightly negative
oxygen atom in neighboring water molecules
9. The sum of the numbers of protons and neutrons
in the nucleus of an atom
10. An atom that has the same number of protons as
other atoms of the same element, but has a different
