The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 11 Na sodium; use: 1156.090 K ...
The melting and boiling points of iodine are the highest among the halogens, conforming to the increasing trend down the group, since iodine has the largest electron cloud among them that is the most easily polarised, resulting in its molecules having the strongest Van der Waals interactions among the halogens.
Sodium carbonate serves as a flux for silica (SiO 2, melting point 1,713 °C), lowering the melting point of the mixture to something achievable without special materials. This "soda glass" is mildly water-soluble, so some calcium carbonate is added to the melt mixture to make the glass insoluble.
The temperature at standard pressure should be equal to the normal boiling point, but due to the considerable spread does not necessarily have to match values reported elsewhere. log refers to log base 10 (T/K) refers to temperature in Kelvin (K) (P/Pa) refers to pressure in Pascal (Pa)
Ionic iodides MI n tend to have the lowest melting and boiling points among the halides MX n of the same element, because the electrostatic forces of attraction between the cations and anions are weakest for the large iodide anion. In contrast, covalent iodides tend to instead have the highest melting and boiling points among the halides of the ...
Terrestrial biota uptake and remove iodine from soil, and bacteria volatilize iodine by methylizing it. [ 1 ] The iodine cycle is a biogeochemical cycle that primarily consists of natural [ 1 ] and biological processes [ 3 ] that exchange iodine through the lithosphere , hydrosphere , and atmosphere .
MeI can also be used to prepare dimethylmercury, by reacting 2 moles of MeI with a 2/1-molar sodium amalgam (2 moles of sodium, 1 mol of mercury). Iodomethane and other organic iodine compounds do form under the conditions of a serious nuclear accident, [ 11 ] after both Chernobyl and Fukushima , Iodine-131 was detected in organic iodine ...
