The radius of the nucleus of is approximately 4.8 pm. What is the average density of the nucleus to one significant figure, assuming it is spherical in shape?
What is the main attractive force between particles in the nucleus of an atom?
The radius of an atomic nucleus, , can be estimated using the equation , where and is the number of nucleons in the nucleus. Assuming the nucleus is spherical in shape, find an expression for the approximate average nuclear density in atomic mass units per unit volume.
