What are 4 properties of calcium?
The metal is trimorphic, harder than sodium, but softer than aluminium. A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns. It is less chemically reactive than alkaline metals and than the other alkaline-earth metals.
What type of metal is CD?
Cadmium
Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.
What are the characteristics of cadmium?
Cadmium is a lustrous, silver-white, ductile, very malleable metal. Its surface has a bluish tinge and the metal is soft enough to be cut with a knife, but it tarnishes in air. It is soluble in acids but not in alkalis. It is similar in many respects to zinc but it forms more complex compounds.
Why calcium is a metal?
calcium is a metal because it is in group 2 which makes it an alkaline earth metal and a powerful reducing agent that loves to react with nonmetals especially powerful oxidizing agents like fluorine and chlorine.
What type of element is calcium?
alkaline-earth metals
calcium (Ca), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. It is the most abundant metallic element in the human body and the fifth most abundant element in Earth’s crust.

When was calcium first discovered?
1808
Calcium/Discovered
Calcium, 20 In 1808 calcium was first isolated by Sir Humphry Davy, a chemist, inventor and at the time Britain’s leading scientist. He conducted many experiments to reduce moist lime by electrolysis, similarly to producing sodium and potassium, with often unsuccessful results.
