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...

There are more than 115 elements known at present and these can be divided into two main groups: Metals Metals are the elements which can form positive ions by losing electrons. For example, Na is a metal because it can form positive ion (Na+) ion by losing an...
