The correct answer is B. Elements are represented by chemical formulas.
Out of the given options, the correct answer is B. Elements are represented by chemical formulas.
Chemical formulas are used to represent compounds, not elements. Elements are pure substances that are made up of only one type of atom and cannot be broken down into simpler substances. They are represented by their chemical symbols, such as H for hydrogen and O for oxygen.
For example, water is a compound made up of two elements: hydrogen and oxygen. The chemical formula for water is H2O, where H represents hydrogen and O represents oxygen.
