However, some metals react slower with water. Non-metals:Non-metals do not react with water. Metals: Most metals do not react with bases. Non-metals react with oxygen in the air to produce non-metal oxides. The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. Copper objects get coated with a green substance called basic copper carbonate with the passage of time. Silver objects become blackened and lose their sheen with the passage of time. Not all metals react with water. Ores which are mined often contain many impurities. Positive ion: A positive ion is formed because of the loss of electrons by an atom. Take some iron filings in a test tube and add some copper sulphate solution with the help of a dropper (test tube A). 3.1.2 Non-metals In the previous Class you have learnt that there are very few non-metals as compared to metals. Following is an example: Manganese dioxide and copper oxide are reduced to respective metals when heated with aluminium. When copper metal is dipped in the solution of aluminium nitrate, no reaction takes place. Alkali metals form ionic compounds The alkali metals form ionic compounds, in which the metal ion has a charge of 1+. Chemical properties of Non-metals Metal + Water → Metal hydroxide + Hydrogen Non-metals have no reaction with water. When steam is passed over magnesium metal, magnesium oxide and hydrogen gas are formed. Rust is iron oxide. Metals and non-metals can take part in oxidation reactions.

The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. Ionic compounds conduct electricity in the molten state. Because copper is less reactive than aluminium. Reaction of Sodium with Water (b) For Non-metals: Generally, most non-metals do not react with water but there are some non-metals which are quite reactive in air like phosphorous, which is very reactive and is kept in water to prevent explosion. Inhaling of carbon monoxide may prove fatal. Some more examples are discussed below. The heavier a metal gets, the slower and more difficult thereaction. Reaction of metals with oxygen Look at how magnesium reacts with oxygen: /**/ The use of a gas jar full of oxygen can be used to combust other metals. Corrosion Iron and many other metals react with oxygen and moisture present in the atmosphere. Reaction with Oxygen Metals: Most metals combine with oxygen to form metal oxides. Metals: Physical properties of metals, chemical properties of metals and non-metal oxide. How was the water formed? Mercury oxide so obtained is again heated strongly. As a result, iron objects become weak with the passage of time. Metals can react with water, acid and oxygen. NCERT Solutions for Class 6, 7, 8, 9, 10, 11 and 12. The product of the reaction between a metal and oxygen is called a _____. When carbon is burnt in an insufficient supply of air, it forms carbon monoxide. Rust is reddish brown in colour and is iron oxide. Reaction of Potassium oxide with Water: Potassium oxide gives potassium hydroxide when reacts with water. Potassium is at the top of the series and hence, most reactive. Both calcium (Ca) and magnesium (Mg) are heavier than water but still float over it: Both calcium and magnesium float over water surface because hydrogen gas is evolved when these metals react with water. Non-metallic Oxide: Non-metallic oxides are acidic in nature. Metals and Non-metals Class 10 Important Questions with Answers Science Chapter 3 Metals and Non-metals Class 10 Important Questions Very Short Answer Type. ; Whether a metal will react depends not only on the other substance, but also the type of metal. These metals cannot be reduced using carbon because carbon is less reactive than them. Non-metals cannot give electrons to hydrogen in water to be released as H2 gas. In this, the ore is heated in the presence of air to convert it into oxide compound. Chemical Properties Of Metals And Nonmetals Chemical properties of metals and non-metals can be divided into five categories: reaction with oxygen, reaction with water, reaction with acids, reaction with bases, and displacement reactions. But all metals … Bring a burning matchstick near the mouth of the test tube. Displacement reactions are explained on the basis of the activity series of metals. Alloys are stronger than the metal from which they are obtained. Reaction of Metal with Water Metals + Water Metal Hydroxide + Hydrogen Example Sodium + Water Sodium Hydroxide + Hydrogen (Na) (H2O) (NaOH) (H2) Reaction of Non-Metal with Water Non Metal + Water No Reaction Example Sulphur + Water No Reaction. Non-metals have no reaction with water. Ionic compounds do not conduct electricity in the solid state. Atomic number of chlorine = 17 Reaction With Acid - Metals react with acids and form salt and hydrogen gas. �Metalloids 4. Mg + H 2 O ⇨ MgO + H 2. 2Al + 3H2O → Al2O3 + 2H2. Non-metals do not react with dilute acids. Updated: Aug 24, 2018. ppt, 149 KB. When steam is passed over magnesium metal, magnesium oxide and hydrogen gas are formed. It is, therefore, kept immersed in kerosene. For example, iron, which is placed higher in the activity series than copper, reacts with copper sulphate solution. Not all metals react this way, but many do. 2. Sulphur dioxide gives sulphuric acid when reacts with oxygen. 5. Thus, ionic bond is formed between sodium and chlorine. Silver metal does not react with copper sulphate solution because silver is less reactive than copper and not able to displace copper from its salt solution. Electronic configuration of chlorine : 2, 8, 7 Reduction of Metal oxide by Heating with Aluminium: Metal oxides are heated with aluminium (a reducing agent) to be reduced to metal. Only a few, like aluminium, zinc, and lead, react with solutions of strong bases like sodium hydroxide to produce a compound of that metal and hydrogen gas. The process is called Corrosion. Some metals like sodium and potassium react vigorously with oxygen. 2. 2Al + 6HCl (Hydrochloric acid) → 2AlCl3 (Aluminium Chloride) + 3H2 (Hydrogen). Sulphur + Oxygen (O2) → SO2 (Sulphur dioxide), The solution of sulphur dioxide turns blue litmus paper red. From the above reactions, we can conclude that the order of reactivity of zinc, copper, and silver is: Zn > Cu > Ag (i.e., zinc is the most reactive of the three and silver, the least reactive). This means magnesium oxide is basic in nature. Copper and silver are also found in the form of sulphide and oxide ores. Silver does not react with copper sulphate. Aim: To prove that iron is more reactive than copper. Since a chemical reaction between an acid and a metal will produce hydrogen gas, this can be used to determine whether a particular metal has reacted with an acid or not. Water can have more energy if it heats up. An amphoteric substance shows both acidic and basic characters. Process of concentration depends upon physical and chemical properties of ores. Sodium chloride is formed because of transfer of electrons. A metal will only react with a salt solution if it is placed higher in the activity series than the metal in the salt. 3. Metal + Water → Metal hydroxide Metals give hydrogen gas when they react with a base. Some metals react with water to form metal hydroxide and hydrogen gas. First of all, concentration is done to remove impurities from ores. Metals like copper, silver, and gold do not react with water under any conditions. Non-metals generally do not react with water. Some metals react with water to form metal hydroxide whereas some of them do not react. References Write a general word equation for this reaction. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Sulphur catches fire when exposed to air. Non-metals generally occur in all the three forms of matter- solid, liquid and gases. Reaction with oxygen Non-metals react with oxygen in the air to produce non-metal oxides. Na + H2O → NaOH (Sodium hydroxide) + H2 (Hydrogen) + Heat, Non-metals generally do not react with water. Zinc reacts with copper sulphate to form zinc sulphate and copper. Types of alloys : Chemical Properties of Metals and Non-metals. Valence electrons = Electrons in outermost orbit = 1 In the long run, the underlying layer of metal keeps on getting lost due to conversion into oxides or sulphides or carbonate, etc. For example, They form negative ions and are good oxidising agents. copper sulphate + water CuSO 4 + H 2 O + copper oxide + sulphuric acid CuO + H 2 SO 4 + water H 2 O + + + MgCl 2 magnesium chloride magnesium oxide hydrochloric acid MgO 2HCl + + + 18.
