Importance
The chapter on "metals and non-metals" is assigned a weightage of \(10\) marks, highlighting its significance in the overall curriculum. Understanding this chapter will enhance the understanding of the properties, reactions, and uses of metals and non-metals.
Also to prepare effectively for related exam questions. It is essential to grasp the various types of properties of metals and non-metals. Reactivity and chemical reactions of metals and non-metals. This chapter gives a well-defined idea on properties of ionic compounds formed by the reaction of metals and non-metals. The final rise of the chapter is on the extraction of metals. Focusing on these concepts will greatly benefit both academic performance and practical application in chemistry.

Learning outcomes
-
Physical properties of metals and non-metals: Let’s take a moment to revisit our discussion on metals and non-metals. A thorough breakdown of the physical properties of both metals and non-metals will enhance our understanding of these materials.
-
Chemical reactions of metals and non-metals with water, oxygen, and acids: A detailed explanation of how metals react with oxygen or air and the reaction rate. Also an overview of how metals react with water, oxygen, and acids.
-
Reactivity of metals and non-metals and ionic properties: A full elaboration on the reaction of metals and non-metals and their reactivity can be studied in detail. The properties of ionic compounds can also be examined.
-
Metallurgy of metals and corrosion: An exhaustive account of the occurrence of metals and the process of ore enrichment. It covers extracting metals from both the middle and low ends of the activity series, as well as the extraction of metals from the higher end of the activity series and the process of electrolytic refining. Additionally, it explains corrosion methods and their prevention.
