Yes. Calcium is an element, and it has the atomic number 20 and Ca is its chemical symbol. It is a metal, and one of the alkali earth metals which are the elements in Group 2 of the periodic table. It is reactive, and as such is not found free in nature, but always appears in compounds with other elements. Wikipedia has additional information, and a link is provided.
No, calcium is an element, which is considered a pure substance because it is made up of only one type of atom.
Organic substances are those that contain carbon. Yes, calcium Carbonate is an organic substance
All compounds are pure substances. This is unless you are referring to a sample of calcium carbonate in limestone, which may be impure due to the presence of impurities.
Pure calcium carbonate doesn't contain any other substances inside.

What kind of pure substance is calcium or carbon?
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
What is pure sample of calcium?
A pure sample of calcium is a silver-white metal that is highly reactive and not typically found in its elemental form in nature. It is commonly found in compound form, such as calcium carbonate in rocks like limestone, or in calcium phosphate in bones and teeth.
Why is calcium carbonate a pure substance but not an element?
Calcium carbonate is a pure substance because it has a fixed composition of calcium and carbonate ions. However, it is not an element because it is a compound made up of multiple elements (calcium, carbon, and oxygen) chemically bonded together.
Is calcium heterogeneous homogeneous mixture?
Calcium itself is an element and is a pure substance, so it is a homogeneous material. It is not a mixture at all.
Is calcium an element compound or mixture?
Calcium is an element. It is a pure substance made up of only one type of atom, specifically calcium atoms.
Is calcium oxide is a pure substance?
Yes. Calcium oxide is a compound which is a type of pure substance.
Is calcuim a mixture or pure substance?
Calcium is an element and therefore a pure substance.
Is calcium oxide a pure substances?
Yes. Calcium oxide is a compound which is a type of pure substance.
Is CaCl2 a pure substance or mixture?
CaCl2 is a pure substance. It is a compound made of calcium and chlorine in a fixed ratio.
What kind of pure substance is calcium or carbon?
Calcium is an example of a pure substance known as an element, specifically a metal. Carbon is also a pure substance, but it is an element that belongs to the non-metal group.
Is calcium chloride and potassium chloride crystals in a beaker a pure substance?
Calcium chloride and potassium chloride are pure substances.
What is the colour of calcium hydroxide?
White as pure, dry substance
What is pure sample of calcium?

Is calcium carbonate an example of a pure substance?
Calcium carbonate can be obtained as an ultrapure chemical reagent.
Why is calcium carbonate a pure substance but not an element?
Calcium carbonate is a pure substance because it has a fixed composition of calcium and carbonate ions. However, it is not an element because it is a compound made up of multiple elements (calcium, carbon, and oxygen) chemically bonded together.
Is calcium oxide a mixture or a pure substance?
ys calcium oxide is a good conductor os electricity
Is calcium heterogeneous homogeneous mixture?
Calcium itself is an element and is a pure substance, so it is a homogeneous material. It is not a mixture at all.
