Atoms and Nuclei

We will learn about the alpha particle scattering experiment and various atomic models in this chapter. It describes the concept of atomic, mass and neuron number. We will also understand Bohr's theory, energy levels and hydrogen spectrum.

In this chapter, we will study the nature and properties of radioactive radiations. It describes the radioactive decay law and radioactive constant. It also discusses the half-life and mean life of radioactive substances.

In this chapter, we will discuss the relation between mass and energy. It talks about the pair-production and pair-annihilation with equations. We will learn the concept of the mass defect and binding energy of the nucleus through a picture.

In this chapter, we will study nuclear fission and nuclear fusion. It explains the chain reaction in nuclear fission and the difference between radioactive decay and nuclear fusion. It discusses the nuclear reactor, its construction and sources of energy.
