Some of the chemical properties of the metals are corrosion resistance, chemical composition and acidity or alkalinity. Iodine is non-metal but it has lustre. 4-8 electrons in the outer shell: Basically, the non-metals outer shell has 4 to 8 electrons, and thus it has the tendency to attract electrons. Non-metals are not lustrous which means they are not shiny. Iron. Gallium and cesium have a very low melting point. Properties of metals have a great impact on how it may perform in a real-life scenario. Metals form cations by losing electrons. docx, 1.19 MB. Metals are elements that form positive ions by losing electrons during chemical reactions, except hydrogen. Non metals are bad conductors of heat and electricity (except graphite).

The lesser the number of valence electrons the more is the activity of the metal. Alkali metals react in following way: 2M + H 2 2M + H -. Metals burning in presence of oxygen within air lead to generating metal oxides. They are very good conductors of electricity and heat. In this unit, we would come across their physical and chemical properties, reactivity series of metals, ionic bonds, and ionic compounds. Some metals react with air and corrode. Non metals have low melting points. Silicon, Arsenic, Germanium .They are called metalloids. Chemical elements lacking these properties are classed Non Metals most non-metallic elements do not possess metallic properties, and in electrolysis the non-metals carry negative charges that are liberated at the anode. In such materials, non-metals are used to increase specific properties. For example - carbon, oxygen, phosphorus etc. Steel - alloy of iron and carbon.
