Science: one of the army of our country

⚔️🔬 Science 🔬⚔️         The importance of science is well known today. Science is not just limited branch, it is very wide branch and extend study of the basics of science makes a new branch of science. For example, Biology is branch in which the study of living being occurred,  Chemistry the study of chemical, Microbiology the study of microorganisms, cell biology the study of all types of cell....etc....etc. But science does not seem to be as important as it should be. Now people understand that there is no alternative without science. Every one know that the science is a great career field, this is also a good education field, that's all there is to it. Still, we can say that ' Science is the one of the army of our country '. What is this nonsense....... How is that........ So let to prove this sentence, with evidence.... At first I would like to say that, we can't imagine the world without Science, because Science has given us so much

Atomic theories

                    * The Atomic theories *
   The atomic theories are the best successful contribution of the scientists, because it's gives most important information, some properties and the concept of atom.
   Before the atomic theory some misunderstanding related to the atoms are created. Scientists find this misunderstanding and solve the all problems related to the atoms by giving the atomic theory to the world.
All the concept of the atom are clear with the atomic theory.
  • Dalton atomic theory :-
Dalton atomic model
  1.   John Dalton proposed that all matter is                 composed Of small ,Hard,Indivisible particles called "Atom".
  2. Atom of given element are identical and have characteristic mass.
  3. Atom combine to form a molecule.                    



  • Thomson atomic theory :-

Thomson atomic model

  1.        J.J. Thomson discovered Electron.
  2.        According to Thomson, atom consist of                 positively charged sphere with negatively                 charged Electrons embedded in it .{Thomson's       atomic model resembles a watermelon}
  3.        Such that atom, as a whole ,has zero charge.

  • Rutherford atomic theory :-
Rutherford experimental model
1.Atom has tiny positively charged core called Nucleus
2. The nuclei surrounded by negatively charged Electrons.
3.An atom electrically neutral ,due to positive charge on nucleus is equal to the negative charge of electrons.             
4.the size of nucleus is about 1,00,000 time smaller than the size of atom .
5.  Atom mostly consists of empty space.               

"The Rutherford model is the landmark in devlopment of modern atomic theory"

Concepts of atom

In Last article We Define  Atom ,  Molecules  & Nuclei.  And the molecule    Atom and atomic concept is the very interesting part and it's not just interesting but important part for chemistry, physics.    Atom is considered as the basic and fundamental unit of the molecule or elements.    Atom is the important back bone of the chemistry, because no one any chemical compound is made up of without atom. Atom is the basic , fundamental and functional unit of the elements is not wrong.     Atomic model and atomic concept of the atom, Scientists gives verious information and the reality of the atom. For the extra and proper information, some scientists like J.J. thomason, John Dalton, and Rutherford gives the atomic theory, due to which the concept of atom for understanding is very easy. Before the atomic theory, we start the concept related to atom.                *  The Concept Related to Atom * In 1808 , John Dalton performed an his experiment and prove that

Units, fundamental quantities and derived quantities.

What mean by Units......? Unit is the basic part of the measurement, because without unit we don not measured anything. Unit:- The reference standard used for the measurement of a physical quantity is called a Unit. System of units:- C.G.S. M.K.S. F.P.S. S.I. units :-            Use of different system of units became very inconvenient for exchanging scientist information between different parts of the world.     Hence, in October 1960 at the Eleventh International General Conference of weights and measures, in Paris, a common system of units called  "System International d' Units"  was accepted.         This system of units called S.I. units consistent of seven fundamental units, two supplementary units and large number of derived units.      Units are classified into two  groups    F undamental units  and  Derived units . The seven basic physical quantities: Length, mass, time, temperature, electric current, lumino

COVID19 : A blessing or A curse

COVID-19 The novel corona or COVID-19 today all world worry about this.  What you need to know about the Corona virus pandemic. What is Corona virus ? People know about Corona virus . the biggest health club and organization like WHO and etc. plays an important role by getting awareness program, scientists and researchers work on Corona virus for getting more information about structure, shape, genetic material and all this is important for making drugs against the corona virus. But at the time of present it's not possible. All countries are contributing to the fight against novel corona virus. Everyone knows how dangerous corona is !!!!! But the truth is something different .  So let's start with my question...... Is Corona really dangerous ???? Yes, is dangerous for human and sometimes animals. Today in the world almost 247 thousands peoples are death due to the corona virus and this chain continues. If you think from the other side...... Corona
