I was wondering how the atoms are arranged... thanks so much :D
limestone is predominantly made up of the mineral calcite (CaCO3)
Trying to describe the structure of Calcite in words is a little hard, so these links will give you some ideas in picture form

limestone is sedimentary, so it is made up of numerous elements.
Limestone is predominately made up of the mineral calcite. CaCO3. This mineral is a tetragonal to hexagonal crystal system. (that describes the symmatry of the mineral.
calcium carbonate
