FAQs on Mindmap: Metals & Non-metals - Science Class 10

1. What are some examples of metals and non-metals?
Ans. Examples of metals include iron, copper, aluminum, and gold. Examples of non-metals include oxygen, carbon, nitrogen, and sulfur.
2. How do metals and non-metals differ in terms of their physical properties?
Ans. Metals generally have a shiny appearance, are good conductors of heat and electricity, and are malleable and ductile. Non-metals, on the other hand, are usually dull in appearance, poor conductors of heat and electricity, and are brittle.
3. What is the significance of metals and non-metals in everyday life?
Ans. Metals are used in various industries for construction, transportation, and manufacturing due to their strength and conductivity. Non-metals are important for biological processes, as they make up essential elements in living organisms and are used in industries for the production of fuels, plastics, and medicines.
4. How do metals and non-metals react with other substances?
Ans. Metals tend to lose electrons and form positive ions when they react with non-metals. Non-metals, on the other hand, tend to gain electrons and form negative ions when they react with metals. These reactions are based on the transfer of electrons between elements.
5. Can elements exhibit properties of both metals and non-metals?
Ans. Yes, some elements, known as metalloids, display properties of both metals and non-metals. Examples of metalloids include silicon, germanium, and arsenic. They can have characteristics such as semi-conductivity and varying degrees of electrical conductivity depending on the conditions.
