Across
- 2. the process in which liquid is converted to a gas
- 4. the melting/freezing point of a liquid under one atmosphere of pressure
- 5. pictures a regular array of metal atoms in a “sea” of valence electrons that are shared among the atoms in a nondirectional way
- 7. some of the interstices (holes) among the closely packed metal atoms are occupied by atoms much smaller than the host atoms
- 9. a solid characterized by the regular arrangement of its components
- 11. the attractive force between the positively charged end of one polar molecule and the negatively charged end of another polar molecule
- 12. the energy required to vaporize one mole of a liquid
- 13. a mixture of elements that has metallic properties
- 14. a solid composed of molecules
- 20. the temperature at which the vapor pressure of a liquid is exactly one atmosphere
- 21. relatively weak intermolecular forces resulting from a temporarily uneven distribution of electrons that induces a dipole in a neighbor
Down
- 1. a solid containing cations and anions that dissolves in water to give a solution containing the separated ions, which are mobile and thus free to conduct an electric cuq
- 3. attraction forces that occur between molecules
- 6. unusually strong dipole-dipole attractions that occur among molecules in which hydrogen is bonded to a highly electronegative atom
- 8. attractive forces that occur between atoms in a molecule; chemical bonds
- 10. a solid that contains atoms at the lattice points
- 15. some of the host metal atoms are replaced by other metal atoms of similar sizes
- 16. the energy required to melt one mole of a solid
- 17. a plot of temperature versus time for a substance, where energy is added at a constant rate
- 18. the pressure exerted by a vapor in equilibrium with its liquid phase at a certain temperature
- 19. the process in which a vapor is converted to a liquid
