Group 0 Elements ( Helium, Neon, Argon...) do not form compounds because they have a complete Octet and are thus unreactive and exist as mono atomic elements
ammonia and chlorine to form ammonium chlorine, 8NH3 + 3Cl2 ---> 6NH4Cl + N2
Calcium (Ca) is the element that may form a compound with CrO4 (chromate). The compound formed would be calcium chromate, CaCrO4.
No. Mercury is an element and oxygen is an element, but together they form a compound.
Lye is a compound. It is composed of sodium hydroxide (NaOH) when in its solid form.
Electricity is a physical phenomenon (flow of electrons in materials) not a compound, mixture or element.

No, argon is not a compound. It is an element classified as a noble gas, existing in its atomic form.
Oxygen is the element. It's a compound because the oxygen bonds with another element to form an oxide.

Neither. It is an element. Also, by definition if a substance is pure it cannot be a mixture; it mus either be an element or a compound.
When you mix an element with a compound, a chemical reaction may occur. The element may react with the compound to form a new compound or may remain unchanged depending on the reactivity of the elements involved.

No, it is an element but as such can form compounds.
Calcium (Ca) is the element that may form a compound with CrO4 (chromate). The compound formed would be calcium chromate, CaCrO4.
When you mix an element with a compound, the element will interact with the components of the compound but will not form a new compound itself. It may bond to some parts of the compound or remain unchanged depending on the specific elements and compounds involved in the mixture.
