Explain the following: (Choose only 4) 

1. 1- Charge density of the core of the nucleus decreases with increasing mass numbers (A). 
2. 2- The total angular momentum of the nucleus for even-even nuclei is equal to zero. 
3. 3- Rutherford and Bohr models have some failure points. 
4. 4- The nuclear forces possess saturation. 
5. 5. From the relation between the average binding energy (Bave) and mass numbers (A) when A>60 the (Bave) becomes decreases.
