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 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...

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...

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...

The number of electrons accepted by a non metal is called valency of the non metal. For example, one atom of chlorine accepts 1 electron to form a negative chloride ion (Cl–), so chlorine is a non-metal. Here because an atom of chlorine gains 1 electron so the valency...
