Calcium.
Calcium carbonate is found in natural sources such as limestone, chalk, and marble. It is also used in many products including antacids, dietary supplements, and as a food additive in baking powder.
Limestone is a form of calcium carbonate that is softer than marble but harder than chalk. It is commonly used in construction materials and can be found in different shades depending on the mineral impurities present.
Two types of limestone are chalk, which is a soft, white sedimentary rock composed of the skeletal remains of marine organisms, and travertine, which is a form of limestone deposited by mineral springs, often found in caves and near hot springs.
CaCO3 is also known as calcium carbonate, which is a common mineral found in rocks such as limestone, marble, and chalk. It is widely used in industries like construction, agriculture, and pharmaceuticals.
Calcium carbonate is also known as limestone or chalk. It is a common compound found in rocks, shells of marine organisms, and minerals. It is used in various industries such as construction, agriculture, and food production.
CALCIUMThis element is calcium (Ca).
Calcium and phosphorus are the two major elements found in milk.
Calcium carbonate is found in natural sources such as limestone, chalk, and marble. It is also used in many products including antacids, dietary supplements, and as a food additive in baking powder.
Chalk is primarily made of calcium carbonate, which is a mineral compound. It is commonly found in the form of limestone or marble. The word "chalk" comes from the Latin word "calx," meaning limestone.
Limestone is a form of calcium carbonate that is softer than marble but harder than chalk. It is commonly used in construction materials and can be found in different shades depending on the mineral impurities present.
The element calcium is found in all four items.
Limestone and Marble have calcite in them.
Calcspar is another word for calcite, a widely distributed crystalline form of calcium carbonate, found as limestone, chalk, and marble.

Chalk is not made of skeletons. It is primarily composed of calcium carbonate, which is a mineral that is found in rocks such as limestone and marble. When chalk is used for writing on chalkboards, the dust particles that are released can sometimes give the appearance of being similar to bone dust, but chalk itself is not made of skeletons.
The common name of Calcium carbonate may be Chalk, but chemically that's not true, if it is the blackboard writing chalk. This chalk is actually Calcium sulfate, which is mistaken as Calcium carbonate, as its manufacturing process uses Calcium carbonate.So, I think the common name for chalk should be Limestone, which is the most common mineral form of this compound.
