A nucleus of stable phosphorus has 15 protons and 16 neutrons. (a) What is its atomic number and mass number ? (b) The nucleus of radio phosphorus has one neutron more than the stable nucleus. What will be its atomic and mass number ? (c ) What will be the atomic number and mass number of new nucleus formed by the decay of a beta -particle by the radio phosporus in part (b) ?

When does the nucleus of an atom tend to be radioactive ?

Assertion (A) : Anything that influences of the valence electorns will affect the chemistry of the element. So, the nuclear molar mass does not affect the valence shell. Reason (R ) : Nucleus contains protons and neutrons, whereas protons i.e. nuclear charge affects the valence shell but neutrons doe not.

Thomson proposed that the nucleus of an atom contains protons and neutrons.

In the nucleus of ._(11)Na^(23) , the number of protons, neutrons and electrons are

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. Volume (V) of the nucleus is related to mass number (A) as
