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.
1.9: Understand that atoms consist of a central nucleus, composed of protons and neutrons, surrounded by electrons, orbiting in shells. The nucleus of the atom contains protons and neutrons. The nucleus is orbited by a number of electrons in a number of shells. The following diagram has only one shell of electrons:
