For example, halogens get darker with increasing atomic weight - fluorine is nearly colorless, chlorine is yellow green, bromine is red brown, and iodine is dark gray/violet. Astatine is sometimes described as probably being a black solid (assuming it follows this trend), or as having a metallic appearance (if it is a metalloid or a metal) The color of the element astatine is unknown. The estimated boiling point is 338 0C; the color may be black. It is impossible for chemists to make a deep study of astatine because they have only.
Astatine is the least reactive of the halogens but just like the rest of them it combines with hydrogen to make hydrogen astatide which dissolves in water to make hydroastatic acid; it is just like a weaker version of hydrochloric acid.

Astatine-211 is the isotope most likely to find clinical use. 210 At decays to polonium-210, an extremely toxic substance notoriously used to murder former Russian spy Alexander V. Litvinenko in 2006 Halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table.The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (salt) and -gen (to produce), because they all produce sodium salts of similar properties, of which. What is Astatine? A highly unstable radioactive element, the heaviest of the halogen series, that resembles Iodine in solution. Astatine occurs naturally in tiny amounts. The chemical properties of Astatine are believed to be similar to those of iodine The Atomic Number of this element is 85 and the Element Symbol is At
The final products of the decay of astatine are isotopes of lead. Following the color trend of the halogens, the elements get darker in color with increasing molecular weight and atomic number. Thus, following the trend, astatine is a nearly black solid, which, when heated, sublimes into a dark, purplish vapor (darker than iodine) Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. A sample of the pure element has never been assembled, because any macroscopic.

Astatine Facts. Astatine (At) has an atomic number of eighty-five. This unstable hallogen wasn't discovered until 1940 and was once believed to be the rarest element on Earth. Astatine was discovered in 1940 by Dale Corson, Kenneth McKenzie, and Emilio Segre at Berkley. It wasn't until three years later, however, that astatine was found in nature Its name comes from the Greek word for unstable, and its longest-lived isotope, astatine-210, has a half-life of just over 8 h. One textbook estimates that less than an ounce of astatine exists on Earth at any moment. That ephemerality means scientists still don't know basic information about the element, like its boiling point or what color. Digital photographs--Color--2010-2020.
