Across
  1. 2. type of bond that involved transfer of electrons, often between metal and nonmetal
  2. 3. subatomic particle, found in nucleus, no charge
  3. 8. energy level or shell of an atom, contains electrons
  4. 11. average kinetic energy of molecules, increases solubility of a solute
  5. 13. a solution that can dissolve more solute
  6. 18. the basic building block of matter
  7. 19. a mixture of solvent and solute
  8. 20. material that dissolves the solute (often a liquid)
  9. 22. subatomic particle, found in nucleus, positive charge
  10. 23. how many molecules of solute are exposed to solvent due to structure, allows for more solubility
  11. 25. number of protons and electrons (if neutral, smaller number on periodic table
  12. 28. a solution with the maximum amount of solute
  13. 29. rows on the periodic table, contain elements with same number of orbitals
  14. 30. distribution of charge in a molecule, can be polar or nonpolar
Down
  1. 1. how readily a solute dissolves in a solvent
  2. 4. organizes elements based on their atomic properties
  3. 5. columns on the periodic table, contain families of elements with same number of valence electrons
  4. 6. the center of an atom, majority of its mass, contains protons and electrons
  5. 7. family of elements (column 18, group VIIIA), 8 valence electrons, stable, doesn't bond
  6. 9. stirring or shaking that increases the solubility of a solute
  7. 10. type of bond that involves sharing of electrons, often between nonmetals
  8. 12. organized on the periodic table, has unique number of protons, neutrons, and electrons
  9. 14. combination of protons and neutrons of an element, bigger number on periodic table
  10. 15. outermost orbital/shell, electrons found here form bonds
  11. 16. metals, family of elements (column 2, group IIA), 2 valence electrons, bonds with VIA
  12. 17. material that dissolves in solvent (often a solid)
  13. 21. family of elements (column 17, group VIIA) has 7 valence electrons, readily bonds with alkali metals
  14. 24. metals, family of elements (column 1, group IA), 1 valence electron, reactive, bonds with halogens
  15. 26. tiny subatomic particle, negative charge, involved in bonding
  16. 27. a solution with more solute than usual due to heating and slowly cooling
