CBSE Class 11 - Chemistry - Chapter - Structure Of Atom - Important Points To Remember


CBSE Class 11 - Chemistry - Chapter - Structure Of Atom - Important Points To Remember (#class11Chemistry)(#NEET)

Structure of Atom


1. Discovery of Electron — Discharge Tube Experiment:

In 1879, William Crooks studied the conduction of electricity through gases at low pressure. He performed the experiment in a discharge tube which is a cylindrical hard glass tube about 60 cm. in length.


Mass of electron = 9.109534 x 10⁻³¹ kg

Charge on a electron = (-) 1.602 x 10⁻¹⁹ C

 

2. Properties of Cathode Rays

(i) Cathode rays travel in straight line.

(ii) Cathode rays start from cathode and move towards the anode.

Physicists and Their Major Contributions (#class11Physics)(#Class12Physics)(#NEET)(#JEE)(#Physics)(#eduvictors)


For Class 11/Class 12 Physics - NEET - JEE

Physics deals with the study of the basic laws of nature and their manifestation in different phenomena. The basic laws of physics are universal and are applied in widely different contexts and conditions. Physics is a basic discipline in the category of natural sciences which also includes other disciplines like Chemistry and Biology. The word physics comes from a Greek word meaning nature.

Here is a partial list of Physicists and their contributions in various fields of physics.
