metals and metalloids

Elements that behave like both metals and non-metals are called metalloids. Common metal, non-metals and metalloids Metals Non-metals Metalloids Gold Oxygen Silicon Silver Car..

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..

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 group of elements r..

(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..

Group 15 of the Periodic table includes five elements namely nitrogen (N), phosphorus (P), arsenic (As) antimony (Sb) and bismuth (Bi). This group is regarded as nitrogen family. There is a transition from non-metallic to metallic character as we go down the group. Nitrogen and ..

Group 15 Elements (Nitrogen Family) - Introduction - Group 15 of the Periodic table includes five elements namely nitrogen (N), phosphorus (P), arsenic (As) antimony (Sb) and bismuth (Bi). This group is regarded as nitrogen family. There is a transition from non-metallic to metallich..

All elements in the periodic table have been classified as metals and non-metals. The non-metals are placed on the right hand side of the periodic table. Non-metals are simple small molecules that are mostly gases. Elements between metals and non-..

At the turn of the nineteenth century, about 30 elements were known. 50 years later by the 1850s, scientists had discovered sixty three chemical elements and the numbers kept increasing. With the discovery and study of more and more elements and their compounds, the various data about them also in..
