Periodical development of fundamental particles and structure of atoms can be explained from different atomic models .

Explanation:

Periodical development of fundamental particles :

About 2600 years ago  an Indian sage called kanada proposed that all forms of matter are composed of very small particles called as Anu  and each Anu  is made up of smaller particles called Parmanu .

Later Greek philosopher Democritus called these atoms and according to him  atoms are indivisible and indestructible .

But Later John Dalton's postulate which suggests that atom  is indivisible  is disproved  by various experiments conducted by various scientists   :                                                                                                              

 1. Electron -  J.J Thomson discovered the electron while experimenting with cathode rays   in 1897.                                                                                              

2.  Proton - Proton was discovered by Gold stein in 1920.                              

3. Neutron was discoverer by James Chadwick   in 1932 by bombardment of alpha particle at beryllium .                                                                         Structure of atom :  

Schrodinger's model of atom : This model  is most precise model and  is used  in present days . According to him  electrons are present in a particular region or space around the nucleus called as orbitals where probability of finding the electrons are more.          

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
