Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds. [9] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen.
Albert Ghiorso (July 15, 1915 – December 26, 2010) was an American nuclear scientist and co-discoverer of a record 12 chemical elements on the periodic table. His research career spanned six decades, from the early 1940s to the late 1990s.
The common watersnake is found throughout eastern and central North America, from southern Ontario and southern Quebec in the north, to Texas and Florida in the south. The Northern Watersnake (Nerodia s. sipedon) naturally occurs as far west as Colorado , east of the Rocky Mountains , commonly found in riparian ecosystems along several river ...
N. cyclopion differs from most other species of North American water snakes by having one or more small scales under the eye, giving the appearance of a ring of small plates around the eye, a character shared with the species N. floridana. [8] A heavy-bodied snake, N. cyclopion is dark green, olive, or brown dorsally. Ventrally, it is yellowish ...
Moscovium (115 Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no known stable isotopes. The first isotope to be synthesized was 288 Mc in 2004. There are five known radioisotopes from 286 Mc to 290 Mc. The longest-lived isotope is 290 Mc with a half-life of 0.65 seconds.
Due to how widespread and extremely common they are in the wild, water snakes of the genus Nerodia are often found in the exotic pet trade, throughout the United States, though they are rarely captive bred. Their relative physical plainness, compared to other available pet snake species, and their propensity to bite make them less than ...
The Natricinae are a subfamily of colubroid snakes, sometimes referred to as a family (Natricidae). [1] The subfamily comprises 36 genera.Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes.
The only snake-infecting Dracunculus species known in North America is D. ophidensis. It was originally described in garter snakes in Michigan and Minnesota by Sterling Brackett in 1938, and has since been reported in blackbelly garter snakes from Mexico, as well as northern water snakes and a plain-bellied water snake in Michigan.
