What is the total charge of the uranium nucleus? For the special case of a hydrogen atom, the force between the electron and proton is an attractive Coulomb force. For heavier nuclei like 208 Pb (or targets like depleted uranium and gold with similar N/Z), the flavor dependence scales roughly as N/A. As two particles are brought closer together, the value of F (force or energy) becomes more negative, which means that the particles are more attracted to each other. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators. Because it is so dense, DU is also used in shielding, in the keels of boats and more controversially, in the noses of armour-piercing weapons. While this yields a 25% larger effect than for 48 Ca, these high-Z nuclei have much larger radiative and Coulomb corrections, and generate much larger radiation backgrounds at the same thickness as the 48 . To convert this to coulombs, multiply the number N by the factor {eq}1.6\times 10^{-19} {/eq} to get the value of the charge in coulombs. Legal.
