From a chemical point of view, nonmetals may be divided into two classes: 1) covalent materials, which contain atoms having small sizes, high electronegativities, low valence vacancy to electron ratios, and a pronounced tendency to form negative ions in chemical reactions and negative oxidation states in their compounds; 2) ionic materials, which contain both small and large atoms. Properties of metals can be explained in terms of metallic structure and bonding. In this chapter we will learn about metals and non-metals. 9434 Views. Carbon exists as two distinct isotopes, Graphite and Diamond. Ans: A chemical element (such as boron, carbon or nitrogen) that lacks metal properties and is capable of forming anions, acid oxides, acids, and stable hydrogen compounds. Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Metals and non-metals are two different classes of materials.

Non-metals are oxidizing agents As discussed early, non-metals accept electrons from other substances. What are nonmetal and metal? It is colourless and odourless, insoluble in water and less dense that air. The gases are mixed with more air and passed up a tower of glass beads that have water flowing down. The two forms have identical atoms but it is the way in which atoms are bonded that makes the forms different. Take a good look at the periodic table: Metals: 1. A glowing splint is put into oxygen and it relights. Malleability is the ability of a material to deform when compressed â gold is very malleable and can be beaten to an extremely thin sheet.
