The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods ") and columns (" groups "). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order ...
University of Kansas. Mary Elvira Weeks (April 10, 1892 – June 20, 1975) was an American chemist and historian of science. Weeks was the first woman to receive a Ph.D. in chemistry at the University of Kansas and the first woman to be a faculty member there. Her book Discovery of the Elements is considered the "first connected narrative of ...
Mary Engle Pennington (1872–1952), American chemist. Agnes Pockels (1862–1935), German chemist. Anna Sundström (1785–1871), Swedish chemist. Clara Immerwahr (1870–1915), First woman to get her doctorate in chemistry in Germany. Ellen Swallow Richards (1842–1911), American industrial and environmental chemist.
The discoveries of the 118 chemical elements known to exist as of 2024 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesize more elements, and it ...
Helium, titanium, selenium, palladium, promethium, cerium, europium, mercury, thorium, uranium, neptunium and plutonium are all given names connected to mythological characters. With some, that connection is indirect: europium: named for the continent that had been named after Europa.
Ida Freund (5 April 1863 – 15 May 1914) [1] was the first woman to be a university chemistry lecturer in the United Kingdom. [2] She is known for her influence on science teaching, particularly the teaching of women and girls. She wrote two key chemistry textbooks and invented the idea of baking periodic table cupcakes, as well as inventing a ...
