WebbThe uranium atom. On a scale arranged according to the increasing mass of their nuclei, uranium is one of the heaviest of all the naturally-occurring elements (hydrogen is the lightest). Uranium is 18.7 times as dense as water. Like other elements, uranium occurs in several slightly differing forms known as 'isotopes'. WebbChemists define the ionization energy ( I) of an element as the amount of energy needed to remove an electron from the gaseous atom E in its ground state. I is therefore the energy required for the reaction. Equation 7.2. Because an input of energy is required, the ionization energy is always positive ( I > 0) for the reaction as written in ...
