Physical Property of Non-Metal - Sonority
Sonority of Non- Metals
Non- metals produce a dull sound when struck with a hard object. Non-Metals are not Sonorous. This means that solid non-metals do not make a ringing sound when we strike them. If we drop a piece of carbon (say, a piece of charcoal) or a lump of sulphur on the floor or strike them with a hammer, we do not hear any ringing sound. This mean that carbon and sulphur non-metals are not sonorous. They are not capable of producing a ringing sound when struck.
As we have discussed al the physical properties of Metal and Non Metals, we shall have a look at the difference between Metal and Non Metal.
