Calcium goes from 0 to +2, losing 2 electrons (oxidation). Phosphorus goes from 0 to -3, gaining 3 electrons (reduction). Balance the changes using electrons: Multiply the number of calcium atoms by 3 and the number of phosphorus atoms by 2. Write the balanced Equation:
In this explainer, we will learn how to write and interpret the notations used in chemical formulas. Molecules and compounds consist of various atoms and ions. Chemists have developed ways to talk about these molecules and compounds to distinguish them from one another and indicate their composition. Let us consider a molecule of water.
