A detailed comparison of properties of metals and non-metals is given in table. Property Metals Non-metals State of matter These are usually solid, except mercury, which is a liquid at room temperature. Gallium and Caesium melt bel..

We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electron transfer or by electron sharing. After this combination, the ..

Characteristics of Metals - 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..

Periodic Table and Valency of Elements - a) Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations..
