What are Metals and Nonmetals?
Metals and nonmetals are two different types of elements that have distinct physical and chemical properties. Metals are typically shiny, malleable, ductile, and good conductors of electricity and heat. Some common examples of metals include copper, iron, gold, and silver. In contrast, nonmetals tend to be dull or brittle solids or gases at room temperature. They have low melting points and poor conductivity. Examples of nonmetals include oxygen, nitrogen, chlorine, and sulfur. These two categories of elements play important roles in the world around us and understanding their properties is crucial to understanding chemistry as a whole.
Properties of Metals vs. Nonmetals.
Understanding the properties of metals versus nonmetals is essential in differentiating between these two types of elements. Metals are known to be shiny, meaning they reflect light well, and are malleable, which makes them deformable without breaking. They are also ductile and can be drawn into wires without breaking. Additionally, metals have high thermal and electrical conductivity levels compared to nonmetals. On the other hand, nonmetals tend to have lower melting points and aren't typically conductive to electricity or heat. They also lack the shiny appearance that metals exhibit but may be more brittle or gaseous at room temperature compared to metals. By identifying the properties of both metals and nonmetals, students can better understand their characteristics and how they respond chemically in various settings.

Metals and Nonmetals class 8 Extra Questions and Answers
What is the difference between metals and nonmetals? Answer: Metals are generally shiny, ductile, malleable, and good conductors of heat and electricity. Nonmetals, on the other hand, are dull, brittle, and poor conductors of heat and electricity.
Give an example of a metal that is a good conductor of heat and electricity. Answer: Copper is a good conductor of heat and electricity.
Give an example of a nonmetal that is a poor conductor of heat and electricity. Answer: Carbon is a poor conductor of heat and electricity.
Why are metals used in making cooking utensils? Answer: Metals are good conductors of heat, so they can quickly heat up and distribute heat evenly. This makes them ideal for making cooking utensils.
Why are nonmetals used to make electrical switches? Answer: Nonmetals are poor conductors of electricity, which makes them ideal for making electrical switches as they do not allow electricity to flow through them.
What happens when a metal and a nonmetal react? Answer: When a metal and a nonmetal react, they form an ionic compound.
Name two metals that are used for making coins. Answer: Copper and nickel are two metals that are commonly used for making coins.
Name two nonmetals that are used in making fertilizers. Answer: Nitrogen and phosphorus are two nonmetals that are used in making fertilizers.
Why are metals shiny? Answer: Metals are shiny because they reflect light due to the presence of free electrons.
Why are nonmetals dull? Answer: Nonmetals are dull because they do not have free electrons to reflect light.
Q: What are metals and non-metals? A: Metals and non-metals are two categories of elements in the periodic table. Metals are generally solid, shiny, malleable, ductile, and good conductors of heat and electricity, while non-metals are usually gases or solids that are dull, brittle, and poor conductors of heat and electricity.
Q: What is the difference between metals and non-metals? A: The main difference between metals and non-metals is their physical and chemical properties. Metals are generally shiny, malleable, ductile, and good conductors of heat and electricity, while non-metals are dull, brittle, and poor conductors of heat and electricity. Metals tend to lose electrons to form positive ions, while non-metals tend to gain electrons to form negative ions.
Q: What are some common examples of metals and non-metals? A: Common examples of metals include iron, copper, gold, silver, aluminium, and zinc. Examples of non-metals include hydrogen, helium, carbon, sulfur, chlorine, and nitrogen.
Q: Can elements be both metals and non-metals? A: No, elements are either metals or non-metals based on their physical and chemical properties. However, some elements have properties that fall between those of metals and non-metals and are referred to as metalloids.
Q: What are some uses of metals and non-metals? A: Metals are used for a wide range of purposes, including construction, electrical wiring, transportation, and jewelry making. Non-metals are used for things like fuel, fertilizer, and building materials.
Q: What is the reactivity series of metals? A: The reactivity series of metals is a list of metals arranged in order of their reactivity with other substances. The most reactive metals, such as potassium and sodium, are at the top of the series, while the least reactive metals, such as gold and platinum, are at the bottom. The reactivity series is important for predicting how metals will react with other substances and for understanding how metals are extracted from their ores.
Q: What are some common compounds of metals and non-metals? A: Common compounds of metals include metal oxides, metal hydroxides, metal chlorides, and metal sulfates. Common compounds of non-metals include non-metal oxides, non-metal halides, and non-metal hydrides.
Q: How do metals and non-metals combine to form compounds? A: Metals and non-metals combine to form compounds by transferring electrons from the metal to the non-metal. The resulting compound is held together by ionic bonds, which are formed by the attraction between the positively charged metal ion and the negatively charged non-metal ion.
