  1. 5. / Of, relating to, or characterized by covalent bonds.
  2. 6. / Any state with energy greater than the ground state.
  3. 7. / A property of an atom which increases with its tendency to attract the electrons of a bond.
  4. 9. / A set of rules that are used to determine the term symbol that corresponds to the ground state of a multi-electron atom.
  5. 10. Principle that states that two or more identical fermions cannot occupy the same quantum state simultaneously.
  6. 11. / The chemical bond characteristic of metals, in which mobile valence electrons are shared among atoms in a usually stable crystalline structure.
  7. 12. / A type of chemical bond that involves the electrostatic attraction between oppositely charged ions.
  8. 13. / When atoms combine to form molecules they generally each lose, gain, or share valence electrons until they attain or share eight.
Down
  1. 1. States hypothetically, electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels.
  2. 2. / the smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms.
  3. 3. / The basis of all chemical reactions is the tendency of chemical elements to acquire stability.
  4. 4. / Lowest-energy state of a quantum mechanical system.
  5. 8. states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number.
