Theory

Number Name Description
1. Introduction to structure of the atom This theory explains various elements of the atom discovered by scientists.
2. Atomic structure: Thomson's Model Dalton's atomic theory was made invalid by the discovery of two fundamental particles within the atom by J. J. Thomson. Let us learn 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. 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.
