dull grayish silver
Yes, it's a crystalline form of calcium carbonate.
Calcium is a crystalline solid. The Alkaline Earth Metals have been tested many times but the only crystalline solid is Calcium.
Yes, calcium nitrate is an ionic crystalline salt of calcium normally encountered as the tetrahydrate, Ca(NO3)2.4H2O
Calcium is a malleable, ductile, silver-white, relatively soft metal with face-centered, cubic crystalline structure.
Calcium is solid at room temperature, so it is already "frozen" under normal conditions. In its pure form calcium is a silvery-gray metal.
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.
Calcite: a common mineral consisting of crystallized calcium carbonate.
When calcium and oxygen react, they form calcium oxide (CaO). This reaction is a synthesis reaction and is highly exothermic, meaning it releases a significant amount of heat. Calcium oxide is a white, crystalline solid that is commonly known as quicklime.
Calcium phosphate typically appears as a white powder or solid material. It is often found in a crystalline form and can vary in color depending on the purity and specific composition of the compound.
None. Calcium and oxygen are both elements that can combine to form the compound calcium oxide, CaO.
In its pure form, calcium is a silvery, firm element which is rather malleable. From: http://www.wisegeek.com/what-is-calcium.htm
Calcspar is another word for calcite, a widely distributed crystalline form of calcium carbonate, found as limestone, chalk, and marble.
