Science > Chemistry > Redox Reactions > Oxidation Number or Oxidation State Oxidation Number OR Oxidation State: The donation of electrons is called the oxidation and the gain of electrons is called the reduction. Oxidation and reduction can further be explained by a knowledge of “Oxidation number”. The oxidation state of an atom in its […]

Science > Chemistry > Redox Reactions > Introduction to Redox Reactions In this article we shall study about redox reactions, in which both the oxidation and reduction reactions take place simultaneously. Oxidation: Old Concept: It is a process in which addition of oxygen takes place. 2Mg + O2 → 2MgO It is a […]

Halogens
The five elements; Fluorine (F), Chlorine (Cl), Bromine(Br), Iodine (I) and Astatine (At) belonging to VII A Group of the modern periodic table are collectively referred as halogens. The last element Astatine is radioactive and is very short lived hence generally excluded from the study. The word halogen is derived from the Greek words Halos […]
