Question # 1

Define Half line and discuss its dependence.

Ans 1: The half line T_1/2of a radioactive elements is that period in which half of the atom decay.
Dependence: The number of decaying atoms is proportional to the number of atoms present in the beginning of the period and is proportional to time interval.

Question # 1

Define mass defect and binding energy.

Ans 1: Mass defect: The mass of the nucleus is always less than the total mass of the protons and neutrons that make up the nucleus,The difference of the two masses is called mass defect.
Binding energy:The missing mass is converted into energy at the formation of the nucleus and is called binding energy.

Question # 1

What are thermal reactors?

Ans 1: The thermal reactors are called thermal reactors because the neutrons must be slowed down to thermal energies to produce further fission,They use natural uranium or slightly enriched uranium as fuel.

Question # 1

If nucleus has a life of one year,does this mean that it will be completely decayed after two years?

Ans 1: No it will not decay completely after two years.
Numbers of atom at initial stage =N_o
number of atoms decayed after first year =1/2N_o
