its not an element, therefore it is a compound
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.
Arsenic is a chemical element with the symbol As, atomic number 33.
Sulphur is an element. It is neither compound nor mixture.
Sodium metal is an element, not a compound or a solution. It is a pure substance that consists of sodium atoms.
No, pure gold is not a solution. A solution is a homogeneous mixture where one substance is dissolved in another, whereas pure gold is a metal composed of just one type of atom arranged in a regular pattern.
Gold is an element.
Steam is simply water in a gaseous state, so it is a compound.
It is a diatomic element. As such, it would be a solution. It is not a heterogenous mixture because heterogenous means nonuniform. N2 is uniform because it is composed of all the same element in the same proportion. It's a solution.
Gasoline is best described as a solution. It is a mixture of miscible hydrocarbons.
