By studying the tracks of cosmic ray particles in a cloud chamber in 1932 Carl Anderson discovered a positively-charged particle with a mass seemingly equal to that of an electron. Carl Anderson’s particle was the first antiparticle proven by experiment and was named a “positron”.

Image: Ernest Rutherford (30 August 1871 – 19 October 1937) discoverer of the proton and the father of nuclear physics. The proton is a massive positively charged particle made up of two up quarks and one down quark.
Who proposed Anu and Parmanu?
Kanada proposes that paramanu (atom) is an indestructible particle of matter. The atom is indivisible because it is a state at which no measurement can be attributed. He used invariance arguments to determine properties of the atoms. He also stated that anu can have two states — absolute rest and a state of motion.

Thomson discovered the electron by experimenting with a Crookes or cathode ray tube. He demonstrated that cathode rays were negatively charged. … Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles.
Why did Democritus disagree Aristotle?
Aristotle rejected Democritus’s concept of the atom as it did not agree with his own ideas on nature! Aristotle mistakenly believed matter was made up of only four elements: earth water air and fire. Because of his influence Aristotle’s concept of matter went unchallenged for almost 2000 years!

What did Niels Bohr discover?
What was Niels Bohr’s most important discovery? Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory in that the electrons were limited to specific orbits around the nucleus.
