A list of elements arranged by descending order of chemical activity
Activity series
A list of elements arranged by descending order of chemical activity. Activity series. The activity series is a ranking of elements from most to least reactive, used to predict how they will behave in chemical reactions.

A chemical reaction written using element symbols and chemical formulas
Chemical equation
A chemical reaction written using element symbols and chemical formulas. Chemical equation. A chemical equation is a representation of a chemical reaction using symbols and formulas to show the substances involved.

An equation that shows all ions in a solution, whether or not they participate in a reaction
Complete ionic equation
An equation that shows all ions in a solution, whether or not they participate in a reaction. Complete ionic equation. A complete ionic equation lists all the ions present in a chemical reaction in solution, showing which ions react and which remain unchanged.

An ionic equation that shows only the particles that undergo a change in a reaction
Net ionic equation
An ionic equation that shows only the particles that undergo a change in a reaction net ionic equation. A net ionic equation simplifies a chemical reaction by showing only the substances that actually participate in the reaction.
