what are its isotopes?
One stable isotope and 33 radio isotope as in 2003.
Arsenic
Arsenic occurs in nature as a monoisotopic element, composed of one stable isotope, As. As of 2003, at least 33 radioisotopes have also been synthesized
what is the difference between sea otters and seals UNANSWERABLE where are such otters found? Along the coasts of northern and eastern North Pacific Ocean. what is its scientific name? "Enhydra lutris" . who are its predators? Orcas, sea lions, bald eagles, great white sharks in the water and coyote s, and bears on land. do these otters have social structures? They tend to rest together in single-sex groups called rafts consisting of 10 to 100 animals. how do they forage? They take short dives to the sea floor, may turn over rocks in search of prey like fish , snails and other organisms. At times it amy also carry a rock in the pouch across its chest to break open shellfish and clams. who is the first person to describe them? Georg Steller. who is he? He was a naturalist. how does sea otter impact the economy? Sea otters are blamed for declines in shellfish harvest. However, they help the kelp harvesting industry and also pose as a major tourist attraction. in which religion does the above mentioned fish harvested have dietary restrictions? The Jews and the Seventh-day Adventists. mention a few toxic contents in it? Arsenic and toxins released by dinoflagellate. is the first content a chemical element? Yes, it is. is it used in treatment? It is used for locating tumors, for treating trypanosomiasis and other diseases. how much of it is legally allowed in foods? 23ppb for inorganic arsenic in apple and pear juices as per the limits set by the U.S. Food and Drug Administration. what is its classification? Elemental arsenic and arsenic sulfate and trioxide compounds are classified as "toxic" and "dangerous for the environment" in the European Union. for what kind of preservation is it used in the us? For wood preservation. how do bacteria interact with this chemical element? Many species of bacteria can transform arsenite to arsenate in anoxic conditions by using arsenite as an electron donor.

Arsenic [SEP] Isotopes
Arsenic occurs in nature as a monoisotopic element, composed of one stable isotope, As. As of 2003, at least 33 radioisotopes have also been synthesized, ranging in atomic mass from 60 to 92. The most stable of these is As with a half-life of 80.30 days. All other isotopes have half-lives of under one day, with the exception of As ("t"=65.30 hours), As ("t"=26.0 hours), As ("t"=17.77 days), As ("t"=1.0942 days), and As ("t"=38.83 hours). Isotopes that are lighter than the stable As tend to decay by β decay, and those that are heavier tend to decay by β decay, with some exceptions.
