Calcium sulfate is a compound with the chemical formula of #CaSO_4#. It is made up of a calcium cation #(Ca^(2+))# and a sulfate anion #(SO_4^(2-))#. When a compound is made up of a metal cation and a polyatomic anion, the compound is considered to be ionic.

However, the compound itself has both ionic and covalent bonds in it.
