A.They have too low a ratio of protons to neutrons in the nucleus B.They have too high a ratio of protons to neutrons in the nucleus C.They have too low or too high a ration of protons to neutrons in the nucleusD.They have too low a ratio of protons to electrons in the atom 2.An unstable nucleus A.May have too many neutrons B.May have too few neutrons C.Loses energy by emitting radiation D.All of the above 3What thickness of material is necessary to stop an alpha particle?A.Three feet of concrete B.Three inches of lead C.Sheet of aluminum foil D.Sheet of paper
Number one is C they have too low or too high ratio of protons to neutrons in the nucleus, under going beta decayUnless you know how many protons it has exactly it cannot be A or Belectrons have nothing to do with decay so D is out of the questionQuestion 2 is D all of the above I do not like the wording on C it does not lose energy it transfers it to its surroundings but I understand what it's trying to sayQuestion 3 A sheet of paper is sufficient to stop an alpha particleAll an alpha particle is a 4He which interacts with the air right away and dissipates quite rapidly.
