FAQs on Mind Map: Metals & Non-metals - Subject-Wise Mind Maps for Class 10

1. What are the main differences between metals and non-metals?
Ans. Metals are generally good conductors of heat and electricity, have high melting and boiling points, and are malleable and ductile. Non-metals, on the other hand, are poor conductors, have lower melting and boiling points, and are often brittle in solid form.
2. How do metals and non-metals react with acids?
Ans. Metals typically react with acids to produce hydrogen gas and a salt. For example, zinc reacts with hydrochloric acid to form zinc chloride and hydrogen. Non-metals, however, do not react with acids in the same way and may not produce hydrogen gas.
3. Can you give examples of common metals and non-metals?
Ans. Common metals include iron, copper, aluminum, and gold. Examples of non-metals are oxygen, nitrogen, sulfur, and carbon. Each plays a vital role in various chemical processes and applications.
4. What are the physical properties of non-metals?
Ans. Non-metals generally have lower density, are not shiny, and can exist in all three states of matter (solid, liquid, gas) at room temperature. They are usually brittle in the solid state and do not conduct electricity well.
5. How are metals and non-metals used in everyday life?
Ans. Metals are widely used in construction, electronics, and transportation due to their strength and conductivity. Non-metals are essential in various applications, such as oxygen for respiration, carbon in fuels, and sulfur in fertilizers.
