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.
The modern arrangement of the elements is known as the Periodic Table of Elements and is arranged according to the atomic number of elements. Note that an element: 1  consists of only one kind of atom, 2  cannot be broken down into a simpler type of matter by either physical or chemical means, and. 3  can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
