What are some samples of opening remarks for a Christmas party? Electron configuration of Uranium is [Rn] 5f3 6d1 7s2. Therefore its atomic number is 92. Electron Configuration In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element. Chemical Properties of Uranium. Knowing how to find the number of valence electrons in a particular atom is an important skill for chemists because this information determines the kinds of chemical bonds that it can form and, therefore, the element's reactivity.
