ORETD-753 JAV ## Using the correct form with standard for elements Chemical formulas are written using the chemical symbols for the elements. When there is more than one element in the formula, they are usually combined with one or more numerical values. For example, you may wonder why the formula for water is H2O instead of HO2. The answer is that the formula was created with a simple standard that is called atomic notation, and this involves combining the number of atoms with subscribed characters. This allows scientists to reduce the amount of times they have to write a particular element. By using the number of atoms to represent a specific element, the formula is reduced to a much simpler form.
