Question

True or False. Non-metals are sonorous.

Answer 1

Sonority is the property of the metals to make a sound. For that metals must be of low density. It is determined by the elasticity of the metal. We need to find which metals have the property of elasticity to get the answer.

Complete step by step solution:
We distinguish that metals are sonorous. They make the sound when they are trapped together or they collide. It is one of the most significant properties of metals.
(i) Metals have various types of properties and they are sonorous, malleable, and ductile. They are used in various instruments like cymbals and bells because of their sonority property. Apart from metals, non-metals are non-sonorous. They don’t yield a ringing sound when they are struck.
(ii) Because of low electronegativity when they are struck, the electron cloud flows easily and the energy dissipation is low. So this yields the kinetic energy which is essential to make the required sound.
(iii) This permits the entering kinetic energy to be simply propagated in a form of non-equilibrium in the form of a wave. Since metals have high elasticity and these waves move with a high-speed propagation. As metals have high elasticity which is vital for high-speed propagation these sounds can effortlessly propagate inaudible frequencies.
(iv) For example sodium has minimum density and it is also a soft metal and it is not sonorous. Lead is very dense and is not sonorous. Silver has the sonority property and it is said to be sonorous.

Hence the correct answer is False. Non-metals are not sonorous.

Note:
All metals are not sonorous. Lead that has high density cannot propagate kinetic energy effortlessly because of which sonority is not observed. As a result of the properties of metals, they have many uses in everyday life. Non-metals make a dull sound when they are hit with the hammer.
