Albert Einstein was the person who propesed the atomic theory and the study of atoms.
the Greek Philosophers did not test their theory.
No. Scientists have discovered sub-atomic particles such as quarks.
Some key scientists involved in the development of atomic theory include John Dalton, who proposed the atomic theory in the early 19th century based on the idea of indivisible particles; J.J. Thomson, who discovered the electron in the late 19th century; and Niels Bohr, who proposed a model of the atom with quantized electron orbits in the early 20th century.
Bulletin of the Atomic Scientists was created in 1945.
Building an atomic bomb was not an easy thing. It took some scientists to build it.
British Atomic Scientists Association was created in 1946.
Scientists use the symbol "u" to represent atomic mass unit.
IUPAC proposed the atomic weight (243).
No one proposed it. It IS about the atomic number.
The atomic model was developed by various scientists over time, with contributions from Niels Bohr, Ernest Rutherford, and John Dalton. However, the modern atomic model that we use today, with electrons existing in energy levels around a nucleus, was largely proposed by Niels Bohr in 1913.
The first atomic model was proposed by the Greek philosopher Democritus in 442 BC.
