Chadwick contribution to chemistry
The Chadwick atomic theory arose from James Chadwick's discovery of the neutron. Scientists now know that the nucleus of the atom contains both positively charged protons and neutral neutrons, which have the same mass. Chadwick's discovery led directly to the development of the atomic bomb. See more Scientists today envision atoms as being composed of tiny, heavy, positively charged nuclei surrounded by clouds of extremely lightweight, negatively charged electrons. This model … See more A flurry of research into the atomic model occurred at the end of the 19th and well into the 20th century, culminating in the Schrodinger model of the atom, which is known as the cloud … See more The modern conception of the atom retains most of the characteristics of the planetary model established by Rutherford, but with important modifications introduced by Chadwick and Danish physicist … See more Chadwick's discovery forced a revision of the cloud model, and scientists sometimes refer to the revised version as the James Chadwick atomic … See more WebSCIENTIFIC CONTRIBUTIONS Chadwick is best known for his discovery of the neutron in 1932. A neutron is a particle with no electric charge that, along with positively charged …

Democritus, a Greek philosopher, proposed that matter was made up of small, hard, indivisible particles, which he called atoms. Democritus offered no real evidence to support his idea, and it was not widely believed. The development of modern atomic theory begins in the late 1700's.
