Pauli exclusion principles major part is concerned with quantum number of an atom. A clear understanding of Pauli exclusion principle, in what it is important to give concern that is quantum number. Pauli exclusion  principle States that In same orbital two electrons four quantum number never same. In that case it may be possible of same value of quantum number In same orbital maximum three, but never it be four. If two electrons principle quantum  number, azimuthal quantum number and magnetic quantum number be same turned spin quantum number must be different In this case. If In an orbital spin of one electron if clockwise then others spin will be anticlockwise. Quantum Number  With increasing of the complex concept about electrons nature in an atom there needs an integral number to define the electrons behaviour surrounding the nucleus. Types of quantum number There found four types of quantum number. These are principle quantum number, azimuthal quantum number, m

Quantum Number    Quantum number is  very important topics of discussion in chemistry. To explain the position and energy level of electron in an atom quantum number plays an important role in chemistry. Due to having the limitation of Bohrs electronic shell it is necessary to introduce different quantum number. What is quantum number? Quantum number is the numerical value that usually used for determining the energy, position, orientation as well as Goody's behavior of electron In an atom. It gives the description of electrons.  Types of quantum number  There have four kinds of quantum number. These are principal quantum number, azimuthal quantum number, magnetic quantum number and spin quantum number. Why four kinds of quantum number is necessary? Principle quantum which is called Bohr's electronic shell can explain only the spectrum of hydrogen atom. But it faild to explain the spectrun of other atoms. Not only that, but also Zeeman effect and Stark effect i

Electrolysis  Elecrolysis is a process of deposition of electrolytes by electric current. When electric current pass through any electrolytes the constituents of electrolytes decomposed. Just for example if electric current pass through the Hydrochloric acid solution then hydrochloric acid becomes decomposed and produces hydrogen and chlorine nutran molecule. This process of decomposition of hydrochloric acid is termed as electrolysis.  For a better understanding about electrolysis there needs a clear conception about electrolytes. Electrolytes  Electrolytes are these substance that have capability to conduct electric current by forming ions in solution. The examples of most common electrolytes are sodium chloride and hydrochloric acid.  The compound that do not conduct electricity in aolution is called non electrolytes. The examples of non electrolytes are sugar and alcohol. Few terms concerned with electrolysis is given bellow  The important term concerned with

The rate of chemical reaction is related to the active mass of the reactants. Norwegian scientists Guldburg and Wages states an important law that exptesses the relationship between active mass of the reactant and rate of chemical reaction. That is called Law of mass action. Law of mass action  Rate of a chemical reaction is proportional to the active mass of the ractant molecules Law of mass action can explain on the basis of collision theory of molecules. According to the collision theory the  reactants will undergo in reaction when the reactants will take place a collision between themselves. The rate of chemical reaction depends on the number of molecules take places in collision. With the increasing of molecules number available for collision increases the rate of chemical reaction. Hence, it also can say that the rate of chemical reaction is proportional to the It also explains that the rate of chamical reaction is proportional to the active mass of reactants. molar conc
