For the stabilty of any nucleus,

a. Is there any well defined boundary for a nucleus ? b. What is the order of the size of a nucleus? c. How will you conclude that an atom has a lot of empty space ?

If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3 , then the atomic number of this nucleus is

If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3, then the atomic number of this nucleus is

If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3 , then the atomic number of this nucleus is

The activity in any nucleus is measured in

Briefly describe the structre of nucleus and mention its any two function.

Suppose we have one iron nucleus. We know that the entire positive charge of the atom is carried by the nucleus. In order to understand the electric field of nucleus, it is suggested that we shall assume that the entire positive charge of nucleus is uniformly distributed over the volume of the nucleus. Iron is a conductor, and we know that in any conductor charge cannot be distributed over the volume. Is it fine to assume volume distribution of charge inside the nucleus?

Why does the mass of the nucleus not have any significance in scattering in Rutherford's experiment ?

The radius of the platinum atom in a nucleus is 60.2 fermi. Find the volume of the nucleus. Why fermii is used to measure size of a nucleus?
