Ammonia

Ammonia is an important chemical compound having formula NH3. It is prepared from hydrogen and nitrogen by Haber process. In Haber process first of all nitrogen and hydrogen gases are dried and mixed in the ratio of 1:3 by volume. The mixture is then passed over iron...

Hydrogen

Hydrogen is the lightest element. An atom of hydrogen contains one electron and one proton. It is a unique element because it can lose as well as gain one electron. When an atom of hydrogen loses one electron it acts as metal. On the other hand, when an atom of...

Differences between metals and nonmetals

Differences in Physical Properties: Sno. Metals Non-Metals 1 Metals are malleable. Non-metals are non-malleable or brittle. 2 Metals are ductile. Non-metals are non-ductile 3 Metals are good conductors of heat and electricity. Non-metals are bad conductors of heat and...

Chemical properties of nonmetals

Non-metals are also called electronegative elements because the non-metal atom form negatively charged ion by accepting electrons. Following are the important chemical reactions of non-metals. 1. Reaction of Non-metals with Oxygen All non-metals react with oxygen to...

Physical properties of nonmetals

Non-metals are Non-malleable or Brittle:- Non-metals break into pieces when stretched. For example, sulphur and phosphorous are brittle non-metals Non-metals are Non-ductile:- Non-metals cannot be drawn into thin wires i. e. they broke into pieces when stretched...
