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 ...
He was also awarded the 2019 Longstaff Prize for his "outstanding contributions to green chemistry and for participating centrally in the creation of the Periodic Table Videos". [41] At the end of 2023, Poliakoff was elected (in the division of chemistry) a Foreign Academician of the Chinese Academy of Sciences .
Ruthenium is the only 4d transition metal that can assume the group oxidation state +8, and even then it is less stable there than the heavier congener osmium: this is the first group from the left of the table where the second and third-row transition metals display notable differences in chemical behavior.
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.
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]

Pnictogens (nitrogen's periodic table column) show very similar trends in reactivity and acidity of the highest fluorides (pentafluorides) and most common ones (trifluorides), with the said property increasing down the group: NF 3 is stable against hydrolysis, [84] PF 3 hydrolyzes very slowly in moist air, [85] while AsF 3 completely hydrolyzes ...
