Calcium is a reactive chemical element.
Noble gases are usually inert. It is possible, however, to use a noble gas in a compound, such as XeF4, xenon tetrafluoride, but it is not common.
inert as in the inert gases or "noble" gases
The noble gases, column 18 in a wide form periodic table.
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
calcium because there is calcium carbonate but not carbon calciumate
No. Lithium is highly reactive.
Neon is chemically unreactive and stable
Noble gases are usually inert. It is possible, however, to use a noble gas in a compound, such as XeF4, xenon tetrafluoride, but it is not common.

No. argon is chemically unreactive due to the presence of completely filled orbitals.
potassium
The noble gases, column 18 in a wide form periodic table.
The noble gases are almost chemically unreactive and they are located in group 18 of the periodic table.
Calcium oxide, or quicklime, can be decomposed chemically into its components, calcium and oxygen. Calcium is an element and cannot be decomposed chemically.
neon has completely filled energy levels and hence is generally chemically inert (or unreactive).
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
