But different metals react with oxygen at different intensities. Knowing this electrochemical series we will get to know which metal can displace which metal in a chemical reaction. For e.g. So, zinc displaces copper from copper sulphate solution to form zinc sulphate and copper. This happens due to the formation of a colourless solution of zinc sulphate .you will also observe that during this reaction red-brown copper metal deposits on the piece of zinc. • Most metals form metal oxides when they come in contact with the oxygen. If a piece of copper metal is placed in colourless solution of silver nitrate for some time, the colour of the solution becomes blue and a shining white deposit of silver metal is formed on the piece of copper. 5. Magnesium, zinc and iron react with hot water to produce metal oxide and hydrogen gas. They are very good conductors of electricity and heat. Some metals react with air and corrode. 2Zn      +      O2      →      2ZnO (Zinc + Oxygen → Zinc oxide). Are good reducing agents. Metals like sodium and potassium are highly reactive. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. Metals which fall below hydrogen in the reactivity series does not react with dilute acids. Let us start with the chemical properties of metals. Reactivity with water differs from metal to metal. For example: 4. Metals also generally have certain distinguishing physical properties that make them easy to identify and classify. There are exception to this. Free electrons: Metals … So, copper displaces silver from silver nitrate solution to form copper nitrate and silver metal. But, all metals do not react with water at equal intensity. 2Na  +  2HCl   →   2NaCl  +  H2 (Sodium + Hydrochloric acid → Sodium chloride + Hydrogen), Mg  +  2HCl  →  MgCl2  +  H2 (Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen), Zn  +  2HCl  →   ZnCl2 +  H2 (Zinc + Hydrochloric acid → Zinc chloride + Hydrogen), 4. Iron. 3. Zinc metal burns in air only on strong heating to form zinc oxide. Amphoteric oxides mean that they are acidic as … Chemical Property of Non Metals: Usually have 4-8 electrons in their outer shell. The have lustreand a metallic appearance. • Metals lose electrons easily. They mostly have a very high melting point. Form oxides that are basic. Metals are arranged according to the electrode potential of metals. Generally, metal oxides are insoluble in water. Acidity and Alkalinity: Acidity is the Acid characteristics of the metals… Metals react with acids and get eroded slowly. Metals react with water to produce metal oxide (or metal hydroxide) and hydrogen gas. Sodium metal reacts with oxygen of air at room temperature to form basic sodium oxide. Chemical Property of Metals: Usually have 1-3 electrons in their outer shell. Some metals react with water to form metal hydroxide whereas some of them do not react. Metals form an alloy with other metals or non – metals. Metallic oxides: Metals can form oxides. All metals react with chlorine to form ionic metal chlorides. Mg + H2O → MgO + H2, Iron is less reactive than sodium, potassium, calcium, zinc and magnesium. Mg + HCl → MgCl2 + H2 These are electronegative elements with high ionization energies. Many metal… The most common chemical property is the type of oxide that the element forms. Generally, metals are in a solid state at room temperature. Lose their valence electrons easily. Except for Mercury. They are usually in the form of a solid at room temperature. For example, sodium metal is always kept immersed in kerosene oil. General Chemical Properties  Metals when burned in the presence of oxygen, they combine with oxygen to form metallic oxides which are basic in nature. Reaction with Oxygen Metals: Most metals combine with oxygen to form metal … The metals which are very reactive can react even with cold water while the other metals react with hot water or with steam. some metal oxides are able to dissolve in water to form metal hydroxides (, Reactivity Series or Activity Series of Metals, Enrichment of Ore or Concentration of Ore, Conversion of Concentrated Ore into Metal Oxide, Methods to Obtain Metals of Very High Purity, Experiment to prove that both air and water are necessary for rusting of iron. (Iron + Copper sulphate(Blue solution) → Iron sulphate(Greenish sol) + Copper(red-brown)). Metals form oxides that are basic, but non-metals form oxides that are acidic. Some metals like sodium and potassium react vigorously with oxygen. Your email address will not be published. 3Fe + 4H2O → Fe3O4 + 4H2.
