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.

no its a heterogeneous
A colloid is not a single compound; it is a mixture with properties between those of a solution and fine suspension.
