Web24 mrt. 2024 · The emissions of the most common forms of spontaneous radioactive decay are the alpha (α) particle, the beta (β) particle, the gamma (γ) ray, and the neutrino. The alpha particle is actually the nucleus of a … WebNuclide: A nuclide is a specific nucleus of an atom characterized by its atomic number Z and mass number A. It is represented as, Where X = chemical symbol of the element, Z = atomic number and A = mass number Isotopes: The atoms of an element which have the same atomic number but different mass number are called isotopes.
Web(v) Any nucleus of mass number ‘A’ has radius, = 0 1 3 Where 0 is linear constant, and 0=1.2×10−15 m. (v) Density of all the nucleus is constant and does not depends on mass number ‘A’. but volume of nucleus and its mass depends on mass number ‘A’. Nuclear Force and Properties of Nuclear Force:- WebAs shown in Figure 22.26, a neutron strike can cause the nucleus to elongate, much like a drop of liquid water.This is why the model is known as the liquid drop model.As the nucleus elongates, nucleons are no longer so tightly packed, and the repulsive electromagnetic force can overcome the short-range strong nuclear force.
