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.
Yes it is one of those things. It is an element.
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.
