These elements have characteristics common to metals and non-metals. For example: Arsenic, tin, bismuth e..

One can easily differentiate between metals and non-metals based on their placement on the Periodic Table of the Elements. The metals are elements (with the exception of hydrogen) that are found to the left of a group of elements referred to as the metalloid..

(with the exception of hydrogen) that are found to the right on the Periodic Table i.e., groups IIIA, IVA and VA. The non-metallic character of these elements increases from top to the bottom of the group. For example, in group VA the first and second members are non-metals, the..

Introduction - There are 109 elements known at present. 92 elements occur in nature, while the rest are man-made. All materials on the Earth are made of these naturally occurring elements. These are classified into metals, non-metals, and metalloids. The occurrence and..

or In metals, either the conduction band is partially filled or overlaps with valence band. There is no forbidden energy gap in between. Even if a small electric field is applied, free electrons start moving in a direction opposite to field and hence a good conductor of electrici..
