Science Solutions from Chapter -1 - Metals and Non-metals
This chapter explains the classification of elements into metals and non-metals. It covers their physical and chemical properties. Further, it explains the various methods of extraction of metals from ores and the reactivity order of metals.
Practice Other Topics from Metals and Non-metals
This topic discusses the elements and their classification into metals and non-metals. It explains metalloids and ores. We will also learn about some special techniques used for the extraction of metals.
This topic describes minerals as the elements or their compounds which are obtained directly from the earth’s crust. Metals can be extracted from their ores. The extraction of metals from their ores involves concentration, conversion into oxide, reduction and refining.
In this topic, we will learn the various properties of metals and non-metals in detail with their examples. With the use of various activities, we will learn the physical properties of metals and non-metals.
In this topic, we will learn the different chemical properties of metals. It explains the formation of ions and reactivity with water, acids and bases along with reactions.
This topic explains that oxidation of the surface of a metal due to the action of atmospheric oxygen and water is known as corrosion. Corrosion of iron is called rusting. It can be prevented by galvanisation, chrome plating, alloy formation and electroplating.
This topic deals with the great uses of metals and non-metals. It also explains the uses of metals and non-metals in antiseptic, jewellery, industries, and decorative items.
In this topic, we will learn about the metalloids in detail. It discusses the properties and characteristic features of metalloids. Examples of metalloids are also included here for a better understanding.
