In an electron scattering experiment designed to investigate nuclear charge distribution, the radius of a helium-4 (24He^{4}_{2}\text{He}24He) nucleus is measured to be 1.90 × 10-15 m.
What is the predicted radius of a lead-208 (82208Pb^{208}_{82}\text{Pb}82208Pb) nucleus based on the relationship between nuclear radius and nucleon number?
