Metals And Non-Metals Case Study Questions With answers
Here, we have provided case-based/passage-based questions for Class 10 Science Chapter 3 Metals And Non-Metals
Case Study/Passage-Based Questions
Question 1:
The arrangement of metals in a vertical column in the decreasing order of their reactivities is called the reactivity series or activity series of metals. The most reactive metal is at the top position of the reactivity series. The least reactive metal is at the bottom of the reactivity series.
Hydrogen, though non-metal, has been included in the activity series of metals only for comparison. Apart from it, the hydrogen atom also has a tendency to lose its valence electron and form a cation that behaves like a metal.
H→H++e−H→H++e−

Case Study 2: Metals and non-metals are two broad categories of elements that exhibit distinct physical and chemical properties. Metals are generally hard, shiny, malleable, and good conductors of heat and electricity. They tend to lose electrons and form positive ions. Common examples of metals include iron, copper, aluminum, and gold. Non-metals, on the other hand, are generally dull, brittle, and poor conductors of heat and electricity. They tend to gain or share electrons and form negative ions. Non-metals include elements such as carbon, sulfur, oxygen, and nitrogen. The periodic table provides a systematic arrangement of elements based on their properties. Metals and non-metals react with each other to form compounds, such as metal oxides and non-metallic chlorides. Understanding the properties and reactivity of metals and non-metals is important in various applications, such as in the construction industry, electrical conductors, and chemical reactions.
