Calcium is the metallic component of the substance limestone. Limestone, or calcium carbonate, is an example of a sedimentary rock.
Chalk is composed of pure calcium carbonate, or limestone.
The metallic element in lime is calcium.

Calcium (Ca)
Calcium
Chalk (calcium carbonate, CaCO3) is found in nature, being a natural product.
The most common material that chalkboards are made out of is porcelain enamel. More information about chalkboards can be found at http://www.answers.com/topic/chalkboard
Chalk (limestone) was traditionally used to make the marking devices used on chalkboards, but not the boards themselves. These were made from slate, a metamorphic rock.
The mineral made up of a calcium compound and commonly found in marble is called calcite. Calcite is a carbonate mineral composed of calcium carbonate (CaCO3) and is often the main component of marble, providing its characteristic white color.
calcium carbonate- CaCO3
It is known as calcite, the main mineral of limestone and marble.

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.
Chalk is mostly calcium carbonate, with the formula CaCo3. It is formed from the crushed bodies of tiny sea creatures, which over eons collected as sediment on sea floors, was uplifted, then worn away by erosion and weathering. Chemically speaking, calcium carbonate is the union of the alkaline earth metal calcium and the polyatomic carbonate ion.
it is one of the following soap or copper or ; limestone or wood or marble or baking powder or chalk which you need to find
'Marble' is meta-formosed limestone or chalk. Limestone or chalk has been subject to either heat and/or pressure, and become the harder shiny rock of marble. Marble is calcium carbonate!!!!
Calcspar is another word for calcite, a widely distributed crystalline form of calcium carbonate, found as limestone, chalk, and marble.
they are both rocks but both formed different ways chalk is formed by dead sea creatures skeleltons build up to form chalk and limestone is formed by shells and very littke amounts of mud and sand
The name of the chemical formula CaCO3 is calcium carbonate. Calcium carbonate is commonly found in rocks and is created when ions in hard water react with carbonate ions to create limescale. The hardness of water is measures in ppm CaCO3.

Potassium is an alkali metal but it is only found in nature as an ionic salt.
