Lab Session 5, Experiment 4 Chemical Nomenclature Objective: To learn how to read and write formulas of compounds Background: Many of the substances you will encounter in this laboratory are ionic compounds. They are made up of ions which have an unequal number of protons and electrons. Ion is a charged species. If an element loses an electron, is it called at cation resulting in a positive charge. If an element gains an electron, is it called an anion resulting in a negative charge.
