Ca is the chemical symbol for calcium, an element. It is an alkali metal with atomic number 20.
-------------------------------------------
The above is true, however if the element Ca is present in a solution then it will be present as part of an Ionic compound in solution, note a solution is not a mixture, element or compound, it is a SOLUTION.
An insoluble compound of Ca could be present in liquid, in which case you would have a suspension. A suspension is a mixture.

Sulphur is an element. It is neither compound nor mixture.
Water is a compound, specifically a chemical compound made up of two hydrogen atoms and one oxygen atom. It is not an element, solution, or heterogeneous mixture.
Paper is a heterogeneous mixture because it is made up of different materials (such as cellulose fibers and various fillers) that are not chemically bonded together. It is not a solution, compound, or element.
