Why are metals lustrous and sonorous?
Answers
Hey mate your answer is here ⬇️
The electrons that are farthest from the nucleus give a metal its shine. Light reflects, or bounces off, these outer electrons. This makes the metal appear shiny. This shiny appearance on the surface of some metals is called luster.
Metals are generally sonorous i. e., they produce sound on being struck by some thing. Metal is capable of giving a deep, resonant sound. Metal makes a ringing sound when hit. Metals are sonorous because electron bonding in metals is highly delocalized due to very low electro negativity.
Answer:
Explanation:
Lustrous => It is the property of many metals (exception, Diamond, a non metal) which makes them shine by reflecting the light falling on their surface, when it is polished, e.g., iron rods, gold, silver. ... The property are called “ductile materials”. Any material with high malleability can be highly ductile.
