  1. 2. state in which atoms or molecules are loosely packed together, and can move past each other
  2. 4. the amount of matter contained in an object
  3. 6. - substances present after a chemical reaction; the outcome
  4. 8. - change in the chemical properties of a substance; results in the formation of a new substance
  5. 11. - mixture in which one substance (solvent) dissolves the other substances (solute)
  6. 13. - number appearing before a chemical formula in a chemical equation denoting how many molecules of that substance are involved in the reaction
  7. 17. - vertical column on the Periodic Table of Elements. All of the elements in a group have similar chemical properties
  8. 18. - describes a substance’s ability to be pounded flat and shaped
  9. 19. anything that has mass and takes up space
  10. 21. - Group 1 of the Periodic Table of Elements; highly reactive, soft, and brittle
  11. 22. a pure substance that cannot be broken down into simpler substances
  12. 23. - force of attraction between atoms in a molecule through sharing or redistribution of electrons
  13. 24. - how many electrons an element tends to give away or receive when bonding
  14. 26. - a process in which chemical bonds are broken and reform in different ways, resulting in the formation of new substances
  15. 28. the amount of space an object takes up
  16. 30. - a chemical reaction in which energy is released (through the breaking of chemical bonds). Feels hot to the touch.
  17. 33. - matter is never created or destroyed; in a chemical reaction, the mass of the reactants is equal to the mass of the products
  18. 35. - a chemical reaction in which products can escape, resulting in a lower mass

  21. 42. - related to the outermost electron orbital of an atom (where bonding takes place)
  22. 45. - horizontal row on the Periodic Table of Elements. All of the elements in a period have the same number of electron orbitals
  23. 46. - part of a solution that is dissolved
  24. 47. negatively charged particle that orbits the nucleus in distinct orbitals (shells)
  25. 50. - elements that are not malleable, not ductile, are poor conductors, and do not have luster
  26. 52. a particular kind of matter with uniform properties
  27. 53. - characteristic of a substance that can be observed or measured without changing the substance
  28. 54. - substances present before a chemical reaction; the “ingredients”
  29. 56. the ratio of an object’s mass to its volume
  30. 57. - shorthand method of describing a chemical reaction
