As a metalloid the chemistry of silicon is largely covalent in nature, noting it can form alloys with metals such as iron and copper. The common oxide of silicon (SiO 2) is weakly acidic. Germanium. Germanium is a shiny, mostly unreactive grey-white solid with a density of 5.323 g/cm 3 (about two-thirds that of iron), and is hard (MH 6.0) and ...
[196] [197] Thus in 1864, the "Manual of Metalloids" divided all elements into either metals or metalloids, with the latter group including elements now called nonmetals. [198]: 31 Reviews of the book indicated that the term "metalloids" was still endorsed by leading authorities, [199] but there were reservations about its appropriateness.
a Group 1 is composed of hydrogen (H) and the alkali metals. Elements of the group have one s-electron in the outer electron shell. Hydrogen is not considered to be an alkali metal as it is not a metal, though it is more analogous to them than any other group. This makes the group somewhat exceptional.
The origin of the Roman god of fire Vulcan has been traced back to the Cretan god Velchanos by Gérard Capdeville, primarily under the suggestion of the close similarity of their names. [52] Cretan Velchanos is a young god of Mediterranean or Near Eastern origin who has mastership of fire and is the companion of the Great Goddess .
Svarog [a] is a Slavic god who may be associated with fire and blacksmithing and who was once interpreted as a sky god on the basis of an etymology rejected by modern scholarship. He is mentioned in only one source, the Primary Chronicle , which is problematic in interpretation.
In chemistry, "iron group" used to refer to iron and the next two elements in the periodic table, namely cobalt and nickel.These three comprised the "iron triad". [1] They are the top elements of groups 8, 9, and 10 of the periodic table; or the top row of "group VIII" in the old (pre-1990) IUPAC system, or of "group VIIIB" in the CAS system. [3]
A third tier may also have existed, made up of specialist deities such as the god of snakebite-cures – his name is unknown, as the biblical text identifies him only as Nehushtan, a pun based on the shape of his representation and the metal of which it was made [40] – and below these again was a fourth and final group of minor divine beings ...
