There is much to be learned when it comes to the properties of these two. For e.g. A large number of metals are available in nature. Both may occur in solid and liquid form. Non-metals react with chlorine to produce covalent chlorides. Non-metals, on the other hand, are materials lacking these properties. The rows of the table are called periods and columns are called groups. For examples, diamond is a good conductor of heat and graphic is a good conductor of electricity. Classification of nonmetals. They cannot be beaten into thin sheets or drawn into wires because of their brittleness. Elements on this line are metalloids or semimetals, which have properties intermediate between those of metals and nonmetals. For example, it may conduct electricity well but is brittle (and therefore, not malleable). Answer. On the other hand, only a few metals like K, Na, Ca, and Mg react with hydrogen to produce metal hydrides. They are soft in nature and are the bad conductor of heat and electricity. Metals and Non-metals Class 10 Important Questions Long Answer Type. The metals are arranged on the left side and the non-metals on the right side of the periodic table. Reaction of Metals with Non-metals Reactivity of elements is the tendency to attain a completely filled valence shell. This video covers the difference between the properties of metals and non-metals, and takes a look at transition metals. Ans: Hydrogen, hydrogen, chlorine, fluorine, carbon, nitrogen, arsenic, phosphorus, selenium are examples of non-metal. If you would like to know Gujarati name of any other metal or non-metal or even mineral, you can contact us through the comment section. They can be classified in a variety of ways depending on what property or characteristic you use as a yardstick. Main articles: Ferrous metallurgy and Non-ferrous metals. Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions: \[\ce{3Br2(l) + 2Al(s) \rightarrow 2AlBr3(s)} \nonumber\] A metal is a material that, when freshly prepared shows a lustrous appearance. Non-metals are brittle. A zigzag line runs down the right side of the table. Hardness: Non-metals are not hard rather they are generally soft. Browse more Topics Under Materials Metals And Non Metals (ii)Mercury is liquid metal, bromine is liquid non-metal. Conversely, non-metals are insulators, and so they do not support conduction of heat and electricity. Metals have a very high melting and boiling point. Non-metals cannot displace hydrogen from dilute acids. Examples of non-metals are Iodine, Bromine, Helium, Neon, and Argon while that of metalloids are Arsenic, Tellurium, Antimony, Polonium, Tennessine, etc. Metals. 2. a)List the names of three nonmetals you are familiar with in your daily life. Physical Properties of Metals. Nonmetals are generally classified into three categories depending on Non- metals are non- malleable and non- ductile. Introduction to Non metals. 2.Mention the names of the metals for the following: (i) Two metals which are alloyed with iron to make stainless steel. E.g. 1.0 Lustre: Not only metals have metallic lustre but certain non-metals like iodine and graphite have also a metallic lustre. Physical properties of non-metals. Copper is used in making electric wires, gold is used to make With the exception of graphite, non-metals are weak hea The term "ferrous" is derived from the Latin word meaning Brittle metal. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide. Refractory metal. In contrast, non-metals are boiled and melted at a relatively low temperature. Chlorine to form ionic metal chlorides with iron to make non-metals boiled!
