Theory
| Number | Name | Description |
|---|---|---|
| 1. | Introduction to structure of the atom | Scientists discovered the elementary particle after a series of experiments. Learn about it. |
| 2. | Atomic Structure: Thomson's Model | Dalton's atomic theory was made invalid by the discovery of two fundamental particles within the atom. J. J. Thomson. Let us find out more about it. |
| 3. | Atomic structure: Rutherford's Model | Rutherford carried out significant research on the atomic model after J. J. Thomson's. Let us study more about it. |
| 4. | Bohr's Model and Electron distribution or Electronic configuration | Neils Bohr suggested a new atomic model to solve the limitations of Rutherford's model. Let us learn about it in detail. |
| 5. | Discovery of neutrons and Valence electrons | Various atomic models have been proposed by various scientists. As a result, we now have a better understanding of the structure of atoms. How many electrons are involved in forming a bond in an atom. Let us take a closer look at it. |
| 6. | Valency and bond formation | Various scientists have proposed various atom models. As a result, we now have a better understanding of the structure of atoms. How many electrons are involved in forming a bond in an atom, and who decides? Let's take a closer look at it. |
| 7. | Atomic number and Mass number | In the case of an atom, the atomic number and mass number are vital. Let's find out more about it. |
| 8. | Isotops and their applications | Many atoms of the same atomic number but different mass numbers have been discovered in some elements. Let us find out more about it. |
| 9. | Isobars and isotones | Isobars and isotopes are completely contradictory. Let's find out more about it. |
| 10. | Laws of chemical combination | Scientists in the 17th century tried to figure out how to change one material into another. They made some broad generalisations at the time. Let us learn about these generalisations. |
| 11. | Gay Lussac’s Law of combining volumes & Quantum numbers | In this theory, we will learn about Gay Lussac's law of combining volume and quantum numbers. |
