  1. CHEMISTRY OF LIFE REVIEW

  2. True or False • Matter (atoms) obey the same rules of chemistry whether they are in living or non living things.

  3. FILL IN THE BLANK • If we take a living thing apart, we eventual end up with ____________

  4. MULTIPLE CHOICE • Life builds from atoms to form many levels of organization. What happens at each new level? • A vital force becomes apparent • Rules of chemistry change • New properties emerge • Nothing changes

  5. LIST • LIST 12 LEVELS OF BIOLOGICAL ORGANIZATION

  6. FILL IN THE BLANK All living and non-living things are composed ________________. HINT-takes up space and has mass

  7. SHORT ANSWER • Where do living things get there matter from?

  8. SHORT ANSWER • Why must matter be recycled?

  9. FILL IN THE BLANK • Matter is composed of ______________ • HINT-A pure substance that can’t be broken down any further by ordinary chemical means

  10. LIST • What are the six elements that make up 98% of living things?

  11. SHORT ANSWER • How can you CHNOPS to evolution?

  12. FILL IN THE BLANK • 3-4 different types of CHNOPS elements combine to make the ______________ of living things. HINT-Two or more different elements chemically combined in a fixed ratio.

  13. SHORT ANSWER • What are trace elements?

  14. FILL IN THE BLANK • Each type of element consists of one type of _____________. HINT-Smallest unit of matter that still retains the properties of an element

  15. MULTIPLE CHOICE • What determines the properties of an element? A. Structure of atom B. Arrangement of atoms within a compound C. Structure of a molecule D. The nucleus of an atom

  16. SHORT ANSWER • What are the three components of an atom?

  17. FILL IN THE BLANKS • The nucleus of an atom contains _________ and _______________

  18. MULTIPLE CHOICE • What forms a cloud around the nucleus of an atom? A. Protons B. Neutrons C. Electrons D. Alpha particles

  19. SHORT ANSWER • Which two subatomic particles make up most of the mass of the atom?

  20. LIST • List the subatomic particles and give their charge.

  21. MULTIPLE CHOICE • What subatomic particle identifies the atom? A. Proton B. Neutron C. Electron D. Alpha particle

  22. MULTIPLE CHOICE • What subatomic particle determines how an atom behaves? A. Proton B. Neutron C. Electron D. Alpha particle

  23. MULTIPLE CHOICE • What subatomic particle determines the behavior of an atom? A. Proton B. Neutron C. Electron D. Both the protons and the neutrons

  24. MULTIPLE CHOICE • The atomic number is the number of: A. Protons B. Neutrons C. Electrons D. Both the protons and the neutrons

  25. MULTIPLE CHOICE • The mass number is the number of: A. Protons B. Neutrons plus electrons C. Electrons plus protons D. Both the protons and the neutrons

  26. SHORT ANSWER • A neutral atom has an atomic mass of 18 and 7 electrons. How many protons and neutrons does it have?

  27. SHORT ANSWER • An atom with a negative 2 charge has an atomic mass of 18 and 7 electrons. How many protons and neutrons does it have?

  28. FILL IN THE BLANK • Two atoms with same atomic number but different mass number are called _______________.

  29. TRUE OR FALSE • Living things are able to distinguish between radioactive isotopes and non radioactive isotopes of same element.

  30. MULTIPLE CHOICE • Why are radioactive isotopes beneficial in biology? • A. They are easily detected an traced. • B. They behave exactly the same way as their nonradioactive isotope partners. • C. living things don’t distinguish a difference between radioactive and nonradioactive isotopes of same element. • D. All are correct

  31. LIST • List five uses of radioactive isotopes in biology:

  32. SHORT ANSWER • How are radioactive isotopes harmful?

  33. SHORT ANSWER • What electrons determine the behavior of an atom?

  34. LIST • List the number of electrons required to fill electron shell 1, 2, and 3

  35. TRUE OR FALSE • If the valence shell is complete it has eight electrons in it except for the first shell which is complete with two electrons.

  36. TRUE OR FALSE • If the valence shell is complete the atom is said to be reactive and unstable.

  37. TRUE OR FALSE • If the valence shell is not filled the atom is said to be reactive and unstable.

  38. TRUE OR FALSE • If an atom is stable and unreactive it will combine and form bonds with other atoms.

  39. TRUE OR FALSE • If an atom is unstable and reactive it will combine and form bonds with other atoms.

  40. SHORT ANSWER • What are the two ways atoms can become stable?

  41. MATCHING A. Valence electrons B. Valence Shell C. Valence Number ____ Number of electrons in outer shell ____ The Number of bonds an atom can make ____ The outer most electron shell

  43. SHORT ANSWER • Why does an atom transfer an electron to another atom?

  44. SHORT ANSWER • When there is a transfer of an electron from one atom to another atom, what happens to the charge on each atom?

  45. SHORT ANSWER • What do we call an atom with a charge?

  46. VERY SHORT ANSWER • Does the chlorine atom have the same properties as its ion?

  47. VERY SHORT ANSWER • Are ionic bonds strong in the aqueous environment of living things?

  48. SHORT ANSWER • Two ions with opposite charge will form what type bond?

  49. SHORT ANSWER • Sharing of electrons is what type of bond?

  50. SHORT ANSWER • Why are the compounds of living things made by combining CHNOPS atoms with covalent bonds?
