FAQs on How Do Metals And Non Metals React Video Lecture - Class 10

1. How do metals and non-metals react differently?
Ans. Metals and non-metals react differently due to their contrasting properties. Metals generally lose electrons to form positive ions, while non-metals tend to gain electrons to form negative ions. This difference in electron transfer leads to variations in their chemical reactivity.
2. What happens when a metal reacts with a non-metal?
Ans. When a metal reacts with a non-metal, an ionic compound is typically formed. The metal donates electrons to the non-metal, resulting in the formation of positively charged metal ions and negatively charged non-metal ions. These oppositely charged ions are held together by strong electrostatic forces, forming an ionic bond.
3. How do metals react with oxygen?
Ans. Metals react with oxygen to form metal oxides. This reaction is commonly known as oxidation. For example, when iron reacts with oxygen in the presence of moisture, it forms iron oxide, commonly known as rust. This reaction is responsible for the corrosion of metals.
4. Do all non-metals react with acids?
Ans. Not all non-metals react with acids. Non-metals such as carbon, sulfur, and nitrogen generally do not react with acids. However, non-metals like hydrogen, chlorine, and bromine can react with acids under specific conditions. The reaction between a non-metal and an acid may result in the formation of a salt and a gas, depending on the specific non-metal and acid involved.
5. How do metals and non-metals react with water?
Ans. Metals react with water to form metal hydroxides and hydrogen gas. The reactivity of metals with water varies. Some metals, like sodium and potassium, react vigorously with water, releasing hydrogen gas and forming metal hydroxides. Non-metals, on the other hand, generally do not react with water, except for a few highly reactive non-metals like chlorine and fluorine, which can react with water to form acids.
