How do you build a model of the element plutonium for a school project?

To build a model of the element plutonium for a school project, you can use materials like clay or foam to represent the atom's nucleus and electrons. Start by creating the nucleus, which contains 94 protons and typically 150 neutrons, using a larger ball for protons and smaller balls for neutrons. Then, use smaller beads or balls to depict the electrons, arranging them in shells around the nucleus according to the electron configuration. Label each part clearly to explain the structure and properties of plutonium.
