Ammonia (NH3)
Ammonia (NH 3 ) - Ammonia (NH 3 ) is an important compound of nitrogen and hydrogen. It is produced by the natural decomposition of animal and vegetable bodies. The death and decay of plants and animals cause the nitrogen compounds present..

Lanthanides are chemically reactive. They react with carbon, hydrogen, oxygen and sulphur and form carbides, hydrides, oxides and sulphides respectively. The oxides formed are M 2 O 3 oxides. They react with water and form insoluble hydroxides. The oxides and hydroxides react ..
Chemical Properties
Differences in chemical properties Metals have 1, 2 or 3 electrons in the outermost shell Non-metals have 4 to 8 electrons in the outermost shell Loses valence electrons and forms cations Gain or share valence electrons and form anions Electropositive Electrone..
Chemical Formula
Chemical Formula - The chemical formula of a substance is the symbolic representation of the actual number of atoms present in one molecule of that substance. Example 1: Formula of one molecule of oxygen is O 2 . It shows that one molecule of oxygen is made up of 2 atoms of it. ..
