Which of the following property is generally not shown by metals?a)Ele...
Metallic properties refer to the characteristic features of metals. Metals are a group of elements that possess certain common properties such as electrical conduction, thermal conduction, malleability, ductility, and a lustrous appearance. However, one property that is generally not shown by metals is dullness.
Dullness refers to the lack of shine or luster in an object. In the context of metals, dullness implies that the surface of the metal does not reflect light and appears matte or non-reflective. This property is typically associated with non-metals or non-metallic substances.
Explanation:
- Reflectivity and Luster:
Metals are known for their characteristic luster or shine. When light falls on the surface of a metal, it gets reflected uniformly, resulting in a shiny appearance. This property is due to the presence of free electrons in the metal lattice, which allows for the easy movement of light waves. As a result, metals are excellent reflectors of light and have a high degree of luster.
- Electrical Conduction:
Metals are excellent conductors of electricity. This property is due to the presence of delocalized electrons in the metal lattice. These free electrons are not bound to any specific atom and can move freely within the metal structure. When a voltage is applied across a metal, these free electrons can easily move and carry the electric current.
- Sonorous Nature:
Metals also possess the property of being sonorous, which means they produce a ringing sound when struck. This property is again related to the presence of free electrons in the metal lattice. When a metal is struck, the force of the impact causes the metal atoms to vibrate. These vibrations are transmitted through the lattice, resulting in the production of sound waves.
- Ductility:
Ductility is the property of a material to be drawn into thin wires without breaking. Metals are highly ductile due to the presence of metallic bonds. Metallic bonds are formed by the sharing of valence electrons between atoms. This arrangement allows the atoms to slide over each other when a force is applied, making the metal malleable and ductile.
In conclusion, metals generally do not exhibit the property of dullness. They are highly reflective and possess a characteristic luster. Other properties exhibited by metals include electrical conduction, sonorous nature, and ductility.

Which of the following property is generally not shown by metals?a)Ele...
Introduction:
Metals are a group of elements that have certain characteristic properties. These properties differentiate metals from non-metals. Some of the commonly observed properties of metals include electrical conduction, malleability, ductility, and sonorous nature. However, there is one property that is generally not shown by metals, and that is dullness.
Explanation:
Dullness:
Dullness is the property of not reflecting light. Non-metals like wood, rubber, and plastic are generally dull in appearance. They do not have a shiny or lustrous surface. On the other hand, metals are known for their characteristic metallic luster. When light falls on the surface of a metal, it gets reflected in a specular manner, giving metals their characteristic shine.
Electrical Conduction:
Metals are excellent conductors of electricity. This means that they allow the flow of electric current through them with ease. The presence of free electrons in the metallic lattice enables metals to conduct electricity efficiently. This property makes metals indispensable in various electrical and electronic applications.
Sonorous in Nature:
Metals also exhibit the property of being sonorous. Sonorous means that metals produce a ringing sound when struck. This property is due to the ability of metals to vibrate at a specific frequency when hit, generating a sound. Non-metals, on the other hand, are not sonorous and produce dull sounds when struck.
Ductility:
Ductility is another property commonly associated with metals. It refers to the ability of metals to be drawn into thin wires without breaking. Metals like copper, gold, and silver are highly ductile and can be stretched into long wires. This property is important in various industries, such as electrical wiring and jewelry making.
Conclusion:
In conclusion, metals generally do not exhibit the property of dullness. They have a characteristic metallic luster and reflect light in a specular manner. The other properties shown by metals include electrical conduction, sonorous nature, and ductility. These properties make metals versatile and useful in various applications.
