Sand is a mixture and rarely is only one compound.
Table salt and water is a solution.

Filtered maple syrup is a solution.
An element is an element and can not, in anyway, be separated.
heterogenous
Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds. If there is water or air flowing though the sand at a fast rate, then it can also be a suspension.

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.
