  2. oxygen has 2 more protons than carbon
  3. carbon has 4 more protons than oxygen
  4. oxygen has 4 more protons than carbon
9. 
Why does the proton determine the identity of an atom?
  1. The number of protons is also the atomic mass.
  2. The number of protons determines chemical properties, such as reactivity.
  3. The number of protons in an atom's nucleus determines an atom's atomic number.
  4. The number of protons decides an atom's name.
 
10. 
Which statement is most correct about the number of protons in an element and periodic table arrangement?
  1. an element in period 4 of the periodic table will have more protons than a period 3 element
  2. an element in period 3 of the periodic table will have more protons than a period 4 element
  3. an element in period 3 of the periodic table will have the same number of protons as a period 4 element
  4. there is no correlation between the period numbers on periodic table and the number of protons in the elements
