FOLLOW UP QUESTION-NUCLEI

1.  THERE ARE NO ELECTRON INSIDE THE NUCLEI.
          a) HOW CAN BETA PARTICLE OR AN ELECTRON COME FROM THE NUCLEUS
          b) HOW CAN GAMA RAY IS EMITTED FROM A NUCLEUS

2.  Q VALUE IS  THE ENERGY CORRESPONDING TO THE DIFFERENCE IN MASS OF THE REACTANT NUCLEONS MINUS THE MASS OF THE PRODUCT NUCLEI.
          a) IF Q VALUE IS POSITIVE,WHAT IS THE NATURE IS THE NUCLEAR REACTION.
          b) IF Q VALUE IS NEGATIVE WHAT IS THE NATURE OF THE NUCLEAR REACTION

3.   a)  IF THE MASS OF THE PRODUCT NUCLEI IS <THE MASS OF THE REACTANT NUCLEI ,WHAT IS THE SIGN OF Q
       b) IS ENERGY ISABSORBED OR RELEASED IN THE ABOVE CASE.

4.  IF 1 Kg  AND  I Gm OF THE SAME RADIOACTIVE MATERIAL ARE TAKEN SEPARATELY.
         a) WHAT IS THE MASS  LEFT AFTER A HALFLIFE
         b) WHAT IS THE MASS LEFT AFTER TWO HALF LIFE

5.   a)  IDENTIFY THE CHARGES ON RADIOACTIVE RAYS
      b) COMPARE THE MASSES OF THE PARTICLES OF THE RADIOACTIVE RAYS

6.  IT IS ESTIMATED THAT THE ENERGY RELEASED IN AN ATOM BOMB EXPLOSION HAS BEEN 7.6x10^13J. IF EACH FISSION RELEASES AN ENERGY OF 2000MeV,CALCULATE THE NUMBER OF ATOM FISSIONED

7.  FIND THE ENERGY IN eV EQUIVLENT TO 1 a.m.u OF MATTER

8.  WHICH ARE THE DIIFFERENT TYPES OF NUCLEAR REACTOR

9.  WHAT ARE THE MAIN PARTS AND FUNCTION OF THE NUCLEAR REACTOR

10.  a)  WHAT IS HALF LIFE PERIOD
       b)  HALF LIFE OF A 3 ELEMENTS ARE GIVEN IN THE TABLE.RANK THE ELEMENTS ACCORDING TO THEIR ACTIVITIES
       RADIUM                  -       1.6X10^3Y
       LANTHUM               -       1.1X10^10Y
       PHOSPHOROUS     -        14.3DAYS

11.  CLASSIFY THE FOLLOWING STATEMENT AS PROPERTIES OF ALPHA PARTICLE AND BETA PARTICLE
     PROPERTIES
  a)  THEY CAN INTERACT WITH ATOM AND AS A RESULT THEY GET SCATTERED WHILE TRAVELLING THROUGH MATTER.
 b) WHILE COMING OUT FROM NUCLEUS THEY SOMETIMES INTERACT WITH ORBITAL ELECTRONS & THEY EJECT SECONDARY ELECTRON FROM ORBIT
  c) THE ENERGY SPECTRUM APPEARS CONTINUOUS DUE TO THE CREATION OF VERY LIGHT PARTICLE CALLED NEUTRINO
   d) THE VELOCITY & K.E OF PARTICLE DEPENDS ON ENERGY OF THE PARENT WHICH EMITS THEM

12.  AN ATOMIC REACTOR IS YIELDING 30,000KW ENERGY PER SECOND. CALCULATE THE NUMBER OF URANIUM ATOM UNDERGO FISSION PER SECOND.GIVE THAT ENERGY PER FISSION IS 200 MeV.
