Discovered the idea about the positively charged particle called “PROTON”

He is a Greek philosopher who began to search for a description of matter.

(English Chemist) performed a number of experiments that eventually led to the acceptance of the idea of atoms.

an English Scientist, provided the first hint that an atom is made of even smaller particles.

Introduced the idea about the negatively charged particle called “electron

He proposed a model of the atom that is sometimes called “Plum Pudding” Mode

an English Physicist, was hand at work on an experiment.

Danish Scientist, proposed an improvement.

brilliant German Physicist, modified Niels Bohr’s atomic theory to include elliptical orbits.

a Physicist and a Biologist, was considered the Father of Quantum Mechanics. Today’s atomic model is based on the principles of wa

Proposed that the electron (which is thought of as a particle) could also be thought of as a wave

Discovered that for a very small particle like the electron, its location cannot be exactly known and how it is moving. This is called UNCERTAINTY PRINCIPE

you can’t locate the exact position of an electron at any given time (too small, too fast)
