# What are the following equations called?

Our teacher was writing out the following ways of expressing redox and she used a particular term for what these equations are called. When we write out the following what is this called? Its a way to show what atoms lose and gain electrons, but I forgot what these are called:

\begin{align} \ce{Li &-> Li+ + e-}\\ \ce{F + e- &-> F-} \end{align}
