Thermionic Emission and Radioactivity

In this topic, we will have a detailed view on nuclear reactors with their process of generation of electricity. It also discusses the fundamental parts required for a nuclear reactor and work function.

In this topic, we will look upon the rate of thermionic emission with the factors affecting it. It also explains the different kinds of thermionic emitters with their applications of thermionic emission.

In this topic, we will study the cathode rays and the experiment of discharge tubes. It also explains the properties, nature and uses of cathode rays. A schematic representation of cathode ray oscilloscope is given to explain the construction and working of it.

In this topic, we will have a detailed study on the structure of the atom using pictorial representations. It discusses subatomic particles including electrons, protons and neutrons. It mentions the charge and mass of these subatomic particles.

In this topic, we will discuss atomic orbitals. It explains what problems persist before the scientists after the discovery of subatomic orbitals. We will also have different models and experiments related to the discovery of atoms.

The concept of isotopes is introduced in this topic. It states that the elements having the same atomic number but different mass numbers are termed isotopes. It also consists of examples to illustrate the concept of isotopes.

This topic describes the concepts of radioactivity and the laws of radioactive decay. It also explains the process of alpha, beta, and gamma decay.

This topic discusses the effects of radioactive radiations with background radiations. A brief on Geiger counter is also given here. Harmful effects and safety measures to be taken are also discussed here.

This topic explains the nuclear reactions which are divided into fission and fusion reaction. It also details the fission reactions and fusion reactions with the pictorial representations and models used for them.
