Nuclear Physics

No. Date Physics Nuclear Physics" Mucleus The entire positive charge and nearly the entre Mass of atom Is concentrated in avery Sarall space called Nucleus. Isotopes the atoms of an element having Same atomic number but different Mass number are called Isotopes Isobar The atoms of different element having Same Mass number but different atobic number 22 called Isobar e.g. IH 2He and 11 Na 10Ne22 are (sobar. Isotones the aToms of different element having different atomic Number and different Mass Number but having Same number of Neutron I Somers Atoms having the Same number and the same atomic Number but different radioactive propertis

No. Date Nuclear Force. The nucleons. Force acting Inside the nucleus or acting between Nuclear force are the strongest Force in nature His Very short range attractive Force. Itis non central and non Conservative Force. ltw Independent of charge. It is 100 time that of electrostashic force. * Mass defect. the deffrence between the Sum ofMasses of All Mucleons cm) and Mass of Macleus (m) Mass defect (AM) = M-m = [ ZZppt +(A-Z)Mn-MN) -
