Question

The metals that produce a sound on striking a hard surface are called:
1. ferrous
2. porous
3. sonorous
4. igneous

Answer 1

Correct Answer - Option 3 : sonorous

The correct answer is sonorous.

• The metals that produce a sound on striking a hard surface are called sonorous metals.
• When we strike these metals, a ringing sound is produced.

• These metals have extremely low negativity.
• The electrons in these metals are not bounded so much and they are delocalised.
• The electrons cloud moves in an easy way.
• The energy is dissipated less.
• The kinetic energy is produced and the sound we hear, when striking on these metals.
• The most sonorous metal is silver.
• The elasticity of silver is high.

• Sodium and potassium are the least sonorous.
• Copper, iron, calcium and magnesium are also sonorous.
• Sonorous metals are also good conductors of heat.
