Non-metals Objective type Questions and Answers
Elements are divided into two main classes: Metals and non-metals. This division is based upon differences in the characteristic properties of the two types of elements. Metals, in general, are solids (except mercury which is a liquid) having a bright appearance (metallic lustre) and are good conductors of heat and electricity. They are malleable (i.e. they can be flattened into thin sheets by hammering) and ductile (i.e. they can be drawn out into wire by stretching). On the other hand, some non-metals are gases, while others are solids (except bromine which is a liquid) which do not posses metallic lustre (except iodine). They are not malleable or ductile.
