PROPERTIES OF METALS

Almost all metals are solid, shiny, and white-gray

They are mostly found on earth in the form of compounds such as carbonates, silicates, phosphates, oxides, sulfides

Almost all Metals are solid, shiny, and white-gray. They have moderate to usually high reflectivity. They are also generally highly dense, except for some, such as alkali metals. They are more malleable and flexible and have medium to high thermal conductivity. Their melting point is often high and they alloy with other metals. 

They are mostly found on earth in the form of compounds such as carbonates, silicates, phosphates, oxides, sulfides, and halides. They are malleable and do not break or crack. They are usually very dense. They melt at high temperatures. They pass electricity and heat. Their surface is polished and shiny and has a metallic gloss. There is a Metal bond between the metal-forming particles They can be mixed

Chemical Properties of Metals: We know that metals are hard, ductile, malleable, good conductors of heat and electricity and have lustre. But some metals appear dull due to the formation of an oxide layer on their surface. Why are oxides layers formed on the surface of metals? This is because most metals are highly reactive and react with atmospheric oxygen and form their oxide. To learn more about the chemical properties of metals, read the below article. Metals are the elements (except hydrogen) which form positive ions by losing electrons (or donating electrons). Metals include iron, aluminium, copper, silver, gold, platinum, zinc, tin, lead, and mercury. Non-metals are the elements that form negative ions by gaining electrons (or accepting electrons). Some of the examples of non-metals are Carbon, Sulphur, Phosphorus, Silicon, Hydrogen, Oxygen, Nitrogen, Chlorine, Bromine and Iodine. Metals and non-metals show different chemical properties. First, we will discuss the chemical properties of metals. When metals are burnt in air, they react with the oxygen of air to form metal oxides. Some metals react with oxygen even at room temperature, while others react only when heated, and still, others react only when strongly heated. Sodium and potassium metals are so reactive that they can react vigorously with oxygen, catch fire, and burn. Hence, potassium and sodium metals are stored in kerosene oil to prevent their reaction with oxygen and moisture. Metals react with water to form a metal hydroxide and hydrogen gas. All the metals, however, do not react with water. Metals react with water to form a metal hydroxide and hydrogen gas. All the metals, however, do not react with water. For example, Metals like aluminium, zinc and iron do not react with either cold water or hot water. However, less reactive metals like copper and silver do not displace hydrogen from dilute acids. All metals that are more reactive than hydrogen, i. This is because the more reactive metals readily give electrons, and these electrons reduce the hydrogen ions of acids to hydrogen gas. Very dilute nitric acid, however, reacts with magnesium and manganese metals to evolve hydrogen gas. The reactions of magnesium and manganese metals with very dilute nitric acid are given below. Ionic chlorides are formed when metals react with chlorine. Metals like magnesium, aluminium, iron, and copper react with chlorine on heating and form respective ionic chloride. Only a few metals such as sodium, potassium, calcium, and magnesium combine with hydrogen and form metals hydride. Non-metals do not react with water or steam to evolve hydrogen gas. This is because non-metals cannot give electrons to reduce the hydrogen ions of water to hydrogen gas. Non-metals do not react with dilute acids. Non-metals do not displace hydrogen from the dilute acids. For example, non-metals like carbon, Sulphur do not react with dilute hydrochloric acid or dilute sulphuric acid to produce hydrogen gas. Non-metals react with chlorine and form covalent chlorides which are generally non-electrolytes. Metals are hard, lustrous, malleable, ductile and good conductors, whereas non-metals are non-lustrous, non-ductile, non-malleable and bad conductors. Metals are more reactive than non-metals. Metals form basic oxides with oxygen, whereas non-metal form acidic oxides or neutral oxides with oxygen. The chemical reaction of metals depends on the reactivity of metals. What are the five chemical properties of metals? Ans: The five chemical properties of metals are- a. Reactions of metals with oxygen b. Reactions of metals with water c. Reactions of metals with dilute acids d. Reactions of metals with salt solution e. Reactions of metals with chlorine. What are the chemical properties of metal and non-metals? Ans: The chemical properties of metals are as follows: Metals form a basic oxide, metal displaces hydrogen from water and dilute acids. The chemical properties of non-metals are as follows: Non-metals form acidic oxides or neutral oxides, non-metal do not react with water and hence do not displace hydrogen from water. Non-metals do not react with dilute acids and hence do not displace hydrogen from dilute acids. What are the physical and chemical properties of metal? Ans: Physical properties of metals: Metals are hard, ductile, malleable, lustrous and good conductors. Chemical properties of Metals : Metals form a basic oxide, Metals displace hydrogen from water, Metal displace hydrogen from dilute acids, Metal forms ionic chlorides with chlorine. These ionic chlorides are electrolytes but non-volatile and Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydride. How many chemical properties do metals have? Ans: Metals have five chemical properties. We hope this article on ‘Chemical Properties of Metals’ has helped you.
