The atomic shell of the atom is composed of electrons that move in concentric orbits around the atomic nucleus. Since the late 19th century with the discovery of the electron, multiple theories about the structure of the atom, and how the electrons moved inside it followed one another.Answer a...
Who discovered the electron? Although J.J. Thomson is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments ...
Who coined the term atom? Atoms and Subatomic Particles: For years, the atom was considered the smallest unit of matter in existence. In 1897, however, that all changed with the discovery of the electron by J.J. Thomson. This was the first known discovery of a subatomic particle. However...

Modern quantum electrodynamics had been created only several years previously, as a direct result of two key experiments at Columbia--the discovery of the anomalous magnetic moment of the electron, and observation of the Lamb shift in the metastable state of hydrogen. A one-year course in ...
whose seminal proteome is well characterized. In this species, studies of sequence variation, including in natural populations, and of gene-specific knockdown in the laboratory, have identified male and female genes whose actions influence and/or correlate with post-copulatory processes in the female....

Who is credited with the discovery of relative dating? Which came first: relative dating or absolute dating? Who discovered radiocarbon dating? Who discovered radiometric dating? Who discovered radioactive dating? What scientists developed the most rules for relative dating?
Who developed the idea of electron shells? Who invented positron emission tomography? In the late 1800s, experiments using cathode ray tubes led to the discovery of the what? Why was the cathode ray tube experiment done? Who built the first cyclotron?
