FAQs on Index: Metals & Non-Metals - Science Class 10

1. What are the properties of metals and non-metals?
Ans. Metals are typically shiny, malleable, and good conductors of heat and electricity. They are also ductile and have high density. In contrast, non-metals are generally dull, brittle, and poor conductors of heat and electricity. They have low density and are not malleable or ductile.
2. Can you give examples of metals and non-metals?
Ans. Examples of metals include iron, copper, aluminum, gold, and silver. Non-metal examples include carbon, sulfur, oxygen, nitrogen, and chlorine.
3. How do metals and non-metals react with acids?
Ans. Metals generally react with acids to produce hydrogen gas and a salt. For example, when zinc reacts with hydrochloric acid, it produces zinc chloride and hydrogen gas. Non-metals, on the other hand, do not typically react with acids.
4. What are the differences between metals and non-metals in terms of their chemical reactivity?
Ans. Metals are generally more reactive than non-metals. They tend to lose electrons and form positive ions during chemical reactions. Non-metals, on the other hand, are more likely to gain electrons and form negative ions. This difference in reactivity is due to the variation in their electron configurations.
5. How do metals and non-metals conduct electricity?
Ans. Metals conduct electricity because they have a "sea" of delocalized electrons that are free to move throughout the metal lattice. This allows the flow of electric current. Non-metals, on the other hand, do not have this free movement of electrons and therefore do not conduct electricity well, if at all.
