Why is calcium a metal?
Calcium is, however, a metal in its pure form, though rarely seen in this state due to its instability. In air, calcium decomposes rapidly into calcium hydroxide and calcium carbonate. Today, metallic calcium is obtained by displacing calcium atoms in lime with atoms of aluminium in hot, low-pressure containers.
Is CA an element or compound?
calcium
calcium (Ca), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.
Is calcium a good conductor of electricity?
Calcium is harder than lead but can be cut with a knife with effort. While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density.
What is the symbol of phosphorus?

What are the negative effects of calcium?
