Large Office Equipment. Clerical workers must be knowledgeable in the proper operation of office machines such as printers, copiers and fax machines, as well as how to run disposal equipment such as paper and card shredders safely.
Protons, neutrons, and electrons can then organize to form atoms. Atoms are then used to create the molecules around us. As we just learned, there are almost 120 elements that can be found in the molecules we know. Smaller molecules can work together and build macromolecules.
How are electrons placed in shells around the nucleus? Electrons tend to arrange themselves around nuclei so that they have the lowest possible energy. They would all like to get into the lowest energy level, sometimes called the K-shell, but are prevented from doing so by some rules that pop up in quantum mechanics. You can see how electrons are arranged in a particular atom by taking a look at our Periodic Table of Elements.
