 From the list of words above, choose the one that corresponds to the definitions below.

1. Atoms of the same element with different numbers of neutrons. _________________________

2. Different structural forms of the same element.   _________________________

3. The center of an atom that has most of the mass of the atom.     _________________________

4. The region surrounding the nucleus of an atom, which represents the most probable location of the electron.    _________________________

5. A physical property of a metal that means that it can be drawn out into wires.      _________________________

6. A physical property of a metal that means it can be hammered or pounded into many shapes including thin sheets.   _________________________

7. A positively charged subatomic particle found in the nucleus of an atom.       _________________________

8. A neutral subatomic particle found in the nucleus of an atom. _________________________

9. A subatomic particle that moves freely around  the nucleus of an atom and has a negative charge.      _________________________

10. A notation of one or two letters that represents an element. _________________________

11. Elements that are shiny, good conductors of heat & electricity, and that can be pounded into various shapes.    _________________________

12. Elements that lack luster, that generally do not conduct electricity or heat, and that are not ductile or malleable    . _________________________

13. Elements that have properties of both metals and nonmetals.  _________________________

14. Vertical columns on the Periodic Table, made up of elements that have similar chemical properties.     _________________________

15. Horizontal rows on the Periodic Table, made up of elements that have different properties.      _________________________

16. Represents the number of protons in the nucleus of an atom of an element. _________________________

17. The number that represents the average mass of all the isotopes of an element. _________________________

18. The sum of the protons and neutrons in an atom.   _________________________

19. A unit of mass defined as one-twelfth the mass of a carbon-12 atom. _________________________

20. Very small particles that make up protons and neutrons.  _________________________

21. A term used to describe each of the fixed amounts of energy an electron in an atom may have.  Electrons in the lowest energy level have the least amount of energy.  Those in lower energy levels are more likely to be found closer to the nucleus than those in higher levels.  _________________________

22. A law which states that the properties of the elements repeat in a regular way if the elements are arranged by increasing atomic number. _________________________

23. The SI unit used to measure the amount of a substance. The number of atoms in 12.000 g of carbon-12, which is equal to
Avagadro's number.      _________________________

24. 6.02 x 1023, the number of particles in a mole.   _________________________

25. A substance that releases hydrogen ions in solution, and has a pH less than 7._________________________

27. A type of substance that can be separated by physical means._________________________

28. A measure of H+ ions concentration of a solution. Used to determine if a substance is an acid or a base. _________________________

29. A solution that has more dissolved solute than is normal for a given temperature. _________________________

30. A solution in which all the solute that a solution can hold at a given temperature has been dissolved. _________________________

31. A solution that is capable of dissolving more solute at a given temperature. _________________________

32. A type of physical property that depends on the stucture of matter in a sample such as density and boiling point. _________________________

33. A type of physical property that depends on the amount of matter contain in a sample such as mass, volume or length. _________________________

34. A type of homogeneous mixture that contains particles that cannot be seen, do not settle, and do not scatter light. _________________________

35. The substance that is dissolved to form a solution. _________________________

36. The substance that dissolves another to form a solution. _________________________

37. The scattering of light by tiny particles, usually suspended in fluid. The test used to detect the presence of tiny particles. _________________________

41. A type of pure substance made up of multiple elements. The basic unit will always have the same ratio of the elements. _________________________

42. A type of heterogeneous mixture in which the particles scatter light but do not settle out over time. _________________________

43. A type of heterogeneous mixture containing larger particles which settle out over time. _________________________

44. A type of matter that cannot be separated by physical means. _________________________

45. A type of property that can be measured and observed without changing the composition of the substance, such as
