Calcium is a solid, soft dull grey metal at room temperature :)
In its pure form, calcium is a silvery, firm element which is rather malleable. From: http://www.wisegeek.com/what-is-calcium.htm
Yes, at room temperature and pressure calcium is a solid.
Fluorine in its pure form at room temperature is a pale yellow gas. It is highly reactive and is never found in its elemental form in nature, but rather as compounds with other elements.
Sodium in its pure form at room temperature appears as a shiny, soft, and silvery-white metal. It is highly reactive and easily tarnishes when exposed to air, forming a dull oxide layer on its surface.
Assuming by "normal conditions" you mean room temperature at sea level, pure calcium would be in a solid state.

Calcium is solid at room temperature, so it is already "frozen" under normal conditions. In its pure form calcium is a silvery-gray metal.

Calcium is rarely found in its pure form in nature because it readily reacts with other elements to form compounds. It is most commonly found in the form of calcium carbonate in minerals such as limestone and marble.
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.
To obtain pure crystals of calcium chloride, you can start by dissolving calcium chloride in water to form a saturated solution. Then, allow the solution to cool and evaporate slowly, which will cause calcium chloride crystals to form. Once the crystals have formed, they can be filtered and dried to obtain pure crystal calcium chloride.
ok well pure fluorine is coloured pale yellow, it is a highly corrosive and poisonous gas. it has a vitreous and dull lustre. at room temperature it is a gas.
1. Removing of calcium carbonate: CaCO3 is dissolved in vinegar. 2. Obtaining of pure calcium carbonate: by heating of birds eggshells at moderate temperature, to destroy the proteic matrix.
