  2. a region within which electrons orbit that corresponds to a fixed energy level at a given distance from the atomic nucleus of an atom.
  3. the weak attraction between a hydrogen atom that bears a partial positive charge (due to polar covalent bonding with another atom) and another atom, normally oxygen or nitrogen, that bears a partial negative charge; hydrogen bonds may form between atoms of a single molecule or of different molecules.
