Periodic table. The Periodic Table of Videos has filmed at least one video for each of the 118 elements (from hydrogen to oganesson). [13] They have also filmed several videos that discuss molecules such as D 2 O (heavy water) [14] and sulfuric acid. [15] Also filmed are "Chem definitions" that provide an explanation to words that are used in ...
Poliakoff is the narrator in most of a series of over 600 short videos called The Periodic Table of Videos, [19] [20] a popular science project produced by Brady Haran, originally intended to familiarise the public with all 118 elements of the periodic table.
Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
Scientists are using AI to build a “periodic table of shapes” filled with Fano varieties—the basic “atomic structure” of geometry.

University College Nottingham students received their degrees from the University of London. [18] However, in 1943, the university was granted its royal charter which endowed it with university status and gave it the power to confer degrees. In 1948 University College Nottingham was incorporated as the University of Nottingham. [19]
