Question

‘All matter is composed of very small particles called Parmanu’, was first suggested by:
A.John Dalton
B.J. J. Thomson
C.Kanad
D.William J. Crooke

Answer 1

Hint: An Indian philosopher was the one who actually suggested that all matter is composed of very small particles called Parmanu. Paramanu means atom. Atom is a Greek word. In Greek atoms mean uncuttable.

Complete answer:
Coming to the given options, option A, John Dalton. Dalton is an English chemist who introduced the atomic theory.
Coming to Option B, J. J. Thomson. Joshua Joseph Thomson is a retired American mixed martial artist. He said that all atoms contain tiny negatively charged particles called electrons.
Coming to option C, Maharishi Kanad. He is an Indian philosopher who suggested that all matter is composed of very small particles called ‘Parmanu’.
Coming to option D, William J. Crooke, He is British chemist and physicist discovered the element thallium with the help of spectroscopy.
Therefore Maharishi Kanad, a philosopher suggested that all matter is composed of very small particles called ‘Parmanu’.

So, the correct option is C.

Additional information:
Atom consists of three types of particles called protons, electrons, and neutrons.
Protons are positively charged and present in the nucleus of the atom.
Electrons are negatively charged particles that rotate in a fixed orbit called stationary orbits around the nucleus.
Neutrons are having no charge and present in the nucleus of the atoms.

Note:
All molecules are made up of atoms. Means atoms are the smallest part with which molecules are going to prepare. All matter in nature was ultimately reducible to distinct small particles or atoms.
