Nuclei Physics - Nuclei

Those atoms which have the same atomic number but different mass number are called :

Size of nucleus:

For the stability of radiated nucleus:

The binding energy of a nucleus is equal to :

How many types of nuclear chain reactions are? Write the name of each.

How is the radius of a nucleus related to its mass number?###Write the relation between radius R and mass number A of a nucleus.

What is called nuclear reaction?

What will be the difference in the chemical properties of radioactive isotopes and stable isotopes of an element?

Which physical quantities are conserved in natural and artificial radioactivity?

Define atomic mass unit (amu) and write its equivalent energy.

What is the per nucleon binding energy?

Define nuclear fission reaction.

What is meant by nuclear fusion? What happens in this reaction?

What is meant by nuclear mass defect?

Write any three characteristics of nuclear force.

What is nuclear binding energy?

Calculate the height of the potential barrier for a head-on collision of two deuterons.
(Hint: The height of the potetnial barrier is given by the Coulomb repulsion between the two deuterons when they just touch each other. Assume that they can be taken as hard spheres of radius 2.0 fm.)

The nuclear force does not depend on __________ .

The _________ parts of carbon atom are called one atomic mass unit (a.m.u.).

The nature of nuclear force is __________ .

1 kg mass is equivalent to __________ joule of energy.
