Metals And Non Metals Quiz For Class 8 - Quiz

Do you know metals? This is a 'Metals and non-metals quiz' created for class 8th graders. Most of the metals in existence have the power to conduct electricity, unlike all non-metals. There is much to be learned when it comes to the properties of these two. Do you wish to test out your understanding of the two types of materials? If you said yes, then the quiz below is perfect for you. Give it a shot and see how well you do.

Questions and Answers

1.

If a metal is ___________ it can be drawn into a wire.
- A.
  
  Conductive
- B.
  
  Malleable
- C.
  
  Magnetic
- D.
  
  Ductile
Correct Answer
D. Ductile

Explanation
If a metal is ductile, it means that it can be drawn into a wire. Ductility is the property of a material that allows it to be stretched or deformed without breaking. This property is important in industries such as electrical wiring, where metals like copper and aluminum are drawn into thin wires for conducting electricity. Therefore, the correct answer is ductile.

______________ describes the way a substance reflects light, or SHINES.
- A.
  
  Magnetism
- B.
  
  Brittleness
- C.
  
  Luster
- D.
  
  Ductility
Correct Answer
C. Luster

Explanation
Luster refers to the way a substance reflects light or shines. It is a property that describes the appearance of a material, specifically how it interacts with light. Substances with high luster appear shiny and reflective, while substances with low luster appear dull. This term is commonly used in the context of describing the appearance of minerals or metals.

______________ describes how well the substance can be hammered into sheets.
- A.
  
  Malleability
- B.
  
  Conductivity
- C.
  
  Ductility
- D.
  
  Luster
Correct Answer
A. Malleability

Explanation
Malleability is the property that describes how well a substance can be hammered or rolled into thin sheets without breaking or shattering. It is a measure of a material's ability to undergo plastic deformation under compressive stress. Malleability is an important characteristic for metals, as it allows them to be easily shaped and formed into various structures and objects.

What is the symbol of Iron?
- A.
  
  Fe
- B.
  
  Ke
- C.
  
  Ef
- D.
  
  Ee
Correct Answer
A. Fe

Explanation
Iron is symbolized by the chemical symbol "Fe." This symbol is derived from the Latin word "ferrum," which means iron. The use of symbols in chemistry allows for a concise and universal representation of elements. In this case, "Fe" is the recognized symbol for Iron in the periodic table and is widely used in scientific and chemical contexts.

Which of these is a nonmetal?
- A.
  
  Iron
- B.
  
  Copper
- C.
  
  Coal
- D.
  
  None
Correct Answer
C. Coal

Explanation
Coal is a nonmetal because it is an organic sedimentary rock composed primarily of carbon, along with small amounts of other elements such as hydrogen, sulfur, oxygen, and nitrogen. Nonmetals are elements or compounds that lack metallic properties, such as being lustrous, malleable, and good conductors of heat and electricity. Coal does not possess these characteristics, making it a nonmetal, and coal is mainly composed of carbon. Iron and copper, on the other hand, are metals.

Iron atomic number is
- A.
  
  22
- B.
  
  24
- C.
  
  26
- D.
  
  80
Correct Answer
C. 26

Explanation
The correct answer is 26 because the atomic number of an element represents the number of protons in the nucleus of its atom. Iron, being a transition metal, has an atomic number of 26, which means it has 26 protons in its nucleus.

If a substance breaks easily, it is said to be ________________.
- A.
  
  Magnetic
- B.
  
  Conductive
- C.
  
  Brittle
- D.
  
  Ductile
Correct Answer
C. Brittle

Explanation
Brittle refers to the property of a substance to break easily without significant deformation or plasticity. It is the opposite of ductile, which refers to the ability of a substance to be stretched or drawn into a wire. Magnetic and conductive are unrelated properties that do not describe the tendency of a substance to break easily.

Metals are usually silver-grey in color.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Most metals are indeed silver-grey in color due to the way their electrons absorb and re-emit photons, which results in the characteristic metallic sheen. However, there are exceptions with distinct colors, such as copper (reddish) and gold (yellowish).

Nonmetals are usually GOOD conductors of heat and electricity.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Nonmetals are usually poor conductors of heat and electricity. Nonmetals are usually poor conductors of heat and electricity. Nonmetals have electrons that are highly attracted to the nuclei in nonmetallic substances, whereas metals have free-flowing electrons, allowing metals to conduct heat and electricity easily. Therefore, the statement that nonmetals are usually good conductors of heat and electricity is false.

Nonmetals are not attracted to magnets.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Nonmetals, such as carbon, oxygen, and nitrogen, do not possess magnetic properties. This is because their electron configuration does not allow for the alignment of magnetic moments within their atoms. Therefore, nonmetals are not attracted to magnets. Furthermore, not all metals are attracted to magnets.

Metals are soft and can bend or break easily.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Metals are not soft and do not bend or break easily. In fact, metals are known for their strength and durability. They have high tensile strength and are often used in construction and manufacturing industries due to their ability to withstand heavy loads and resist deformation. Therefore, the statement that metals are soft and can bend or break easily is false.

Metals usually have high melting points.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Metals have high melting points since they exist as crystalline solids. These crystalline solids are held together by metallic bonds wherein the free-flowing electrons are attracted to the positive metallic nuclei.

Metals can be drawn into a wire.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Metals can be drawn into a wire because they have high ductility, which means they can be easily stretched and shaped without breaking. This property is due to the metallic bonding, where metal atoms are arranged in a regular pattern and have loosely held electrons that can move freely. When a metal is subjected to a pulling force, the atoms can slide past each other, allowing the metal to be drawn into a wire. This property is essential in various applications, such as electrical wiring and jewelry making.
