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.
Chemicals are built from atoms and atoms usually behave in predictable ways but to understand how they can do this and why it is so predictable, you need to know about atomic structure first. 1. Protons. Protons are positively charged particles which form part of the nucleus of an atom. Their mass is incredibly small, to write down the actual number is pointless as it is impossible for the human mind to grasp their scale.
