Iodine is a chemical element; it has symbol I and atomic number 53. The heaviest of the stable halogens , it exists at standard conditions as a semi-lustrous, non-metallic solid that melts to form a deep violet liquid at 114 °C (237 °F), and boils to a violet gas at 184 °C (363 °F).
· Symbol Hg is from Latin hydrargyrum, which is from the Greek words ὕδωρ and ἀργυρός (hydor and argyros). Meaning "water-silver", because it is a liquid like water (at room temperature), and has a silvery metallic sheen. [3] [55] Thallium (Tl) 81 θαλλός (thallos) Greek "green twig" descriptive
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
The chemical symbol Ag is from the Latin word for silver, argentum (compare Ancient Greek ἄργυρος, árgyros), from the Proto-Indo-European root *h₂erǵ-(formerly reconstructed as *arǵ-), meaning ' white ' or ' shining '. This was the usual Proto-Indo-European word for the metal, whose reflexes are missing in Germanic and Balto-Slavic ...
Iodine is a chemical element with the symbol I and atomic number 53. The name is from Greek ἰοειδής ioeidēs, meaning violet or purple, due to the color of elemental iodine vapor. [17] Iodine and its compounds are primarily used in nutrition, and industrially in the production of acetic acid and certain polymers.
While the symbol is often a contraction of the element's name, it may sometimes not match the element's English name; for example, "Pb" for lead (from Latin plumbum) or "W" for tungsten (from German Wolfram). Elements which have only temporary systematic names are given temporary three-letter symbols (e.g. Uue for ununennium, the undiscovered ...
The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides. A test for the presence of iodide ions is the formation of yellow precipitates of these compounds upon treatment of a solution of silver nitrate or lead(II) nitrate. [2] Aqueous solutions of iodide salts dissolve iodine better than pure ...
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.
