Ferrous and non-ferrous metals. Metals and Non-metals Class 10 Important Questions Long Answer Type. 2.Mention the names of the metals for the following: (i) Two metals which are alloyed with iron to make stainless steel. 3. Some of the common examples of non- metals are carbon, sulphur, iodine, nitrogen etc. Non-metals are brittle. 3.0 Density: Alkali metals have low density. 2. → Atoms of the metals lose electrons from their valence shell to form cation. Non-metals cannot displace hydrogen from dilute acids. They cannot be beaten into thin sheets or drawn into wires because of their brittleness. If you said yes then the quiz … White metal. In this chapter we will learn about metals and non-metals. Over the span of several years, many scientists have stumbled across new and unknown substances which they have taken much time and effort to study and figure out— some of these materials have turned out to be beneficial and valuable to man’s needs, while others, interestingly, simply exist in the environment we live in. Typical nonmetals have a dull, colo… In contrast, non-metals are boiled and melted at a relatively low temperature. For e.g. Both may occur in solid and liquid form. A zigzag line runs down the right side of the table. Question 1. Do you wish to test out your understanding on the two types of materials? Similarities - both are materials. The term "ferrous" is derived from the Latin word meaning ... Brittle metal. Do you remember learning about materials in Grade 4. Metals are the elements which exhibit the highest degree of metallic behavior is known as metals, on the contrary Non-metals are such elements which do not possess any metallic behavior, and Metalloids are those elements, that possess some of the properties like metal, while some like non-metal. 1.0 Lustre: Not only metals have metallic lustre but certain non-metals like iodine and graphite have also a metallic lustre. (ii)Mercury is liquid metal, bromine is liquid non-metal. Ans: A chemical element (such as boron, carbon or nitrogen) that lacks metal properties and is capable of forming anions, acid oxides, acids, and stable hydrogen compounds. Metals and non-metals have particularly distinguishing characteristics which separates them from one another. 2.0 Melting point: Some metals like sodium potassium have low melting point, mercury is liquid at room temperature.Carbon a non-metal has a high melting point. Classification of nonmetals. (a) In the formation of compound between two atoms A and B, A loses two electrons and B gains one electron. There is a total of 92 elements that are known to be found naturally, out of which 70 are metals and 22 are non-metals. Non- metals are non- malleable and non- ductile. In the outer shell, metals consist of 1 to 3 electrons, whereas non-metals consist of 4 to 8 electrons. Can you look around and see if they exist in semiconducting forms, helium.
