ATOMIC THEORY
Electrons have no predictable pattern and move in a region where electrons are likely to found called the electrons cloud.
Erwin Shrodinger & Werner Heisenberg.
He proposed the planetary model.
Niels Bohr 1913
He concluded that the atom must contain a small, dense, positively charged region at its center, which he called the nucleus.
Ernest Rutherford
He discovered the negatively charged components inside the atom through his experiments on cathode ray tubes.
J.J Thomson
He said that atoms are chemically combine in simple, fixed, whole-number ratios to form compounds.
Dalton’s Model
He proposed that matter is composed of vey small, spherical, indivisible particles called atoms.
John Dalton’s Atomic Theory
