Problem: The structure of the atom. A cloud of rapidly moving electrons occupies most of the volume of the atom. The nucleus occupies a tiny region at the center of the atom and is composed of protons and neutrons. The nucleus contains virtually all the mass of the atom.What is the approximate diameter of the nucleus in units of pm?

Problem Details

A diagram shows an atom with a diameter of 1 to 5 angstroms. The tiny nucleus containing protons and neutrons has a diameter of only about 10 superscript negative 4 angstroms; the rest of the atom is volume occupied by electrons.
