STRUCTURE OF THE ATOM WHAT IS AN ATOM? Atoms are made up of three subatomic particles such as electrons, protons and neutrons. Protons have a positive electrical charge, electrons have a negative electrical charge and neutrons have no electrical charge at all. Protons and neutrons are present in a small nucleus at the centre of …
Let’s start the introduction of what is Valency of elements What is Valency? The capacity of an atom of an element to form chemical bonds is known as its valency. It decided by the number of valence electrons in its atom. How to find Valency ( How to calculate valency) The valency of a metal …

THOMSON’S MODEL OF THE ATOM Thomson’s model of an atom is also called the plum pudding model. The plum pudding model is one of the several historical scientific models of the atom. First proposed by J.J. Thomson in 1903 soon after the discovery of the electron but before the discovery of the atomic nucleus. …
Discovery of the neutron, proton and electron Explain Discovery of the Neutron Who discovered neutron? The existence of neutron in the atoms was discovered by James Chadwick in 1932. The neutron is a neutral particle present in the nucleus of an atom. Atoms of all the elements contain neutrons except hydrogen atom which does not …
Let’s start the introduction of the Bohr Model of the Atom. Bohr Model of the Atom A Danish physicist named Neil Bohr in 1913 proposed the Bohr’s atom of the model. Bohr’s atomic model is also known as Bohr Atomic Model or Bohr model. He modified the problems and drawbacks associated with Rutherford’s model of …
Let’s start the introduction of the Rutherford Model of the Atom Rutherford’s model of the atom The Rutherford model of the atom is also called a nuclear atom or planetary model of the atom, a description of the structure of atoms proposed by Ernest Rutherford. An atom consists of a positively charged, dense, and very …
