Nonmetals Properties of Nonmetals Nonmetals occur to the right of the dark zig-zag on the periodic table. They are called metalloids. Nonmetals are poor conductors of heat and electricity. Properties of Metals Conductors Metals are good conductors of electricity and heat Properties of Metals A chemical property of metal is its reaction with water and oxygen. • Non-metals generally have somewhere around 4 to 8 electrons in the outer shell. We associate metals with hard shiny objects, and nonmetals with dull, light objects. Metals are Generally hard in nature… E.g. The lesson covers the complete explanation of class 8 Chapter 4 Metals and Non Metals.Topics covered are Introduction to metals, physical and chemical properties of metals. It loses 1 electron and forms a sodiumion Na + Na Na + + 1 e- AN = 11 EC = 2,8,1 2,8 Mg Mg 2+ + 2 e- AN = 12 EC = 2,8,2 2,8 Non metals :- gain electrons and become negative ions. View US version.

To help you with it, here we list a few physical and chemical properties of metals and non-metals. Let's find out about the properties of metals and nonmetals. The card should have information like name of metal/non-metal; its physical properties, chemical properties and its uses. class eight science metals and non metals chemical properties subject notes ... 8 Science. Reaction with Oxygen (a) For Metals: Generally, when metals are reacted with oxygen they will form metallic oxides. This resource is designed for UK teachers. Carbon (graphite) is a non-metal but possesses high melting point. • Non-metals have high electro-negativity; they are electro-negative elements. This results in corrosion and rust. 1. Non metals are soft. Categories & Grades. Hence, non-metals possess low melting and boiling points, except graphite. bells ,strings of guitar etc. Metals Non-Metals 1 All metals react with oxygen to form metal oxides All non-metals react with oxygen to form acidic or neutral oxides.
