Uranium - Mass Number - Neutron Number - U - Periodic Table
WebEach shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1] WebThe trouble with uranium was that the isotope uranium 235 needed to build a bomb was incredibly difficult to separate from the much less rare uranium 238. They are chemically identical. But if uranium 238 can be encouraged to absorb a slow neutron in a reactor, it becomes the unstable isotope uranium 239. WebSep 8, 2024 · Uranium has 92 electrons. The outermost shell of electrons is called the valence shell. The electrons in the valence shell are responsible for the chemical properties of an element.
