) is one of the most common polyatomic ions in chemistry, found in everything from Epsom salts to car batteries. To understand how it reacts and behaves, we first have to look at its shape. so42 molecular geometry

Why does this geometry matter? In the mineral kingdom, the tetrahedral nature of sulfate is foundational. Minerals like gypsum and barite are built on the stacking of these perfect tetrahedra paired with metal cations. The stability of the tetrahedral shape contributes to the stability of these rocks, which form vast layers in the Earth's crust. | Feature | Assessment | | :--- |

helps explain why sulfate minerals are so stable and why they form the specific crystal structures they do in nature. ) ion? In the mineral kingdom, the tetrahedral nature of
