Provides an overview on the discovery of the electron by the British physicist Joseph John Thomson. Discovery of cathode rays by Julius Plucker in 1858 at the University of Bonn; Two views on cathode rays; Walter Kaufmann an...
An electron is a negatively charged subatomic particle. It orbits the nucleus of an atom, which is composed of positively charged protons and neutrons, which have no net charge.Answer and Explanation: The discovery of the mass of an electron came about through the combined contributions of J.J...
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. ...
Who discovered the electron? AlthoughJ.J.Thomsonis 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 claimed...
- Robert Hooke: He is credited with the discovery of the cell in 1665 when he observed cork under a microscope and coined the term "cell." - J.J. Thomson: He is known for his work on atomic structure, particularly the discovery of the electron, but he did not discover the cell. -...
3. Key Discovery: The first significant observation of chromosomes was made by German biologist Wilhelm Hofmeister in 1848. He was studying plant embryology and observed the compact structures of genetic material during cell division. 4. Significance of Hofmeister's Work: Although many scientists may...

The eventual discovery of element 87 was made in 1939 by a remarkable Frenchwoman,Marguerite Perey, who began life as a laboratory assistant to none other than Marie Curie in Paris. What is the name of element Bk? Berkeliumis a chemical element with symbol Bk and atomic number 97. Classifie...
In 1977, he won a share of the Nobel Prize in Physics for his discovery of electron localization, whereby disordered metals become insula- tors, and for his pioneering work on mag- netism. His studies of superconductors led him to propose how the force carriers between subatomic particles, ...
Suppose that every morning, you check whether the Sun rises. If it doesn’t, you will really be surprised! You’ll have made the discovery of the century! That’s a really exciting payoff, grant agencies should be lining up to pay for… ...
