Let's calculate the density of a nucleus. The most common variety of iron nucleus has 26 protons and 30 neutrons, so A = 56. Find the radius, approximate mass, and approximate density of this nucleus. Review I REFLECT The radius of the iron nucleus is about 4.6 10-15 m on the order of 10-5 of the overall radius of an atom of iron. The density of the element iron (in the solid state iss about 8000 kg/m (8 g/cm), so we see that the nucleus is on the order of 1013 times as dense as the bulk material. Densities of this magnitude are also found in white-dwarf stars, which are similar to gigantic nuclei. A 1 cm cube of material with this density would have a mass of 2.3 1011kg or 230 million metric tons! Part A Practice Problem: 4 Find the approximate mass of the lead nucleus with A= 207, and compare the results with the value for iron. Assume that the total mass is 207 times the mass of a single neutron, ignoring binding-energy corrections. Express your answer in kilograms.
