Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium.
Consequently, is ammonia an element?
Ammonia, NH3, is a chemical compound composed of one nitrogen atom and three hydrogen atoms. Ammonia is a colorless gas that is lighter than air, and can be easily liquefied. Ammonia is a compound normally encountered as a gas and has a strong odor.
Simply so, is antimony a metal?
Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes.
Is calcium a metal or nonmetal Class 10?

What is an element Class 10?
Elements are complete chemical substances which relate to a single entry in the modern periodic table. Elements consist of one kind of atoms only. They cannot be broken down into simpler fragments and can exist as atoms or as molecules.
What is calcium chemical properties?
Calcium’s symbol is “Ca” and has an atomic number 20, with atomic weight 40.078amu. The chemical properties of calcium include its melting point, which is 839.0 +/- 2°C while its boiling point is 1484.0ºC with a valence of 2. This means that calcium needs more than 14 times of needed heat to boil water.
