In 2003, his team began working to create element 113 by bombarding a thin layer of bismuth with zinc ions traveling at about 10 percent the speed of light, Riken said. Isotopes of element 113 have a very short half-life, lasting for less than a thousandth of a second, making...
aThe element X has three isotopes: X-221, X-220, and X-218, with masses 220.9, 220.0, and 218.1 amu. The relative abundances of these three isotopes are 74.22%, 12.78%, and 13.00%, respectively. Calculate the atomic mass of element X. 元素x有三同位素: X-221, X-220和X-218,与大量...
Isotopes All isotopes of americium are radioactive. The most stable is americium-241. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number re...
ALL twenty of astatine's isotopes are radioactive. That means they break down spontaneously and are transformed into other elements. Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's ...
