valence electron → An electron in the outermost energy level of a atom; these electrons are the ones involved in bonding atoms together to form compounds.
specific gravity → The quantity of heat required to change the temperature of 1g of any substance by 1 degree C.
properties → The characteristics of substances that give them unique identities.
hydrogen bond → A covalent bond in which three pairs of electrons are shared between two atoms.
periodic table → A cloudlike region around the nucleus where electrons are located. Orbitals are energy sublevels (s, p, d, f) within the principal energy levels.
