![]() These types of reactions are called displacement reactions.Įxample – Iron is more reactive than copper. The reaction is given below –ĭisplacement Reaction - A more reactive metal displaces a less reactive metal from its salt solution. ![]() Reaction With Base - Metals react with bases such as sodium hydroxide and form salt and hydrogen gas.Įxample – Aluminium metal reacts with Sodium hydroxide and forms sodium aluminate and hydrogen gas. Some metals vigorously react with acids.Įxample – Magnesium metal reacts with hydrochloric acid and forms magnesium chloride and hydrogen. Reaction With Acid - Metals react with acids and form salt and hydrogen gas. When a metal reacts with water, metal hydroxide and hydrogen gas are formed.Įxample – Sodium metal reacts with water and forms sodium hydroxide and hydrogen gas. Reaction with water - Metals react with water. The reactions are given below.Īn aqueous solution of metal oxide turns red litmus paper into blue. When we dissolve magnesium oxide in water, it gives magnesium hydroxide. Reaction with Oxygen – Metals react with oxygen and form metallic oxides which are basic in nature.Įxample –Magnesium is metal and when it reacts with oxygen, it forms magnesium oxide. Chemical Properties of Metals: Some of the chemical properties of metals are given below.It means when we strike them, they make a ringing sound. Metals are lustrous which means they have a shiny appearance. Metals are a good conductor of heat and electricity. It means they possess the property of malleability. Physical Properties of Metals: Some of the main physical properties of metals are given below. The metals are distinguished by their chemical and physical properties such as malleability, ductility, ionization and bonding properties etc.Įxamples of metals are gold, aluminium, iron and magnesium etc. ![]() In this article, we will discuss the properties of metals and non-metals and the difference between the two on the basis of their properties (with exceptions) in detail.Ī metal in chemistry is defined as an element that can easily form positive ions called cations and tends to make metallic bonds. In the following figure the periodic table is given by highlighting metals and non-metals as well as metalloids. While nonmetals are those elements that are not malleable, ductile, sonorous and are poor conductors of heat and electricity. etals are defined as elements that possess properties such as, malleability, ductility, sonorous and good conductors of heat and electricity. It’s important to pick the right material for a job based on its chemical and physical properties.We can distinguish elements into metals and non-metals on the basis of their chemical and physical properties. Whereas normal steel will rust when exposed to air and water.Īnd wood will react with oxygen if heated. Like the stainless steel metal in cutlery, which doesn’t react with food and remains shiny after washing. Sometimes, we choose the right material based on its chemical properties - which describe how reactive it is. ![]() Whereas other materials, like the glass bulb of this lamp, are brittle. Metal is a good electrical conductor.īoth the metal and the plastic can be easily shaped into long flexible wires - we say they’re ductile. The electric current can flow through the inner metal part of the wire to light the lamp. And plastic has a lower melting point too.īut plastic is a good electrical insulator, meaning we can touch the outside of electrical plugs and wires without getting an electric shock. Whereas the plastic of the handle doesn’t conduct heat so well, it’s an insulator. Metal is a good conductor of heat, and has a high melting point, making it good to cook with. Physical properties are the basic features of a material that affects how it behaves in different situations. It’s because of the physical properties of the materials. I’m going to find out why we make frying pans out of metal, and why the case around electrical plugs out of plastic, but not the other way round. ![]()
