Non-metals
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. They are:
- dull (not shiny)
- poor conductors of heat and electricity (they are insulatorMaterial that does not allow charge or heat to pass through it easily.)
- weak and brittleIf something is brittle it is easily broken. (they easily break or shatter when solid)
Most non-metals also have these properties:
- they have a low density (they feel light for their size)
- They are NOTsonorousAble to make a ringing sound when hit. (they do not make a ringing sound when hit)
Eleven non-metals are gases at room temperature, including oxygen and chlorine.
One non-metal, bromine, is a liquid at room temperature.
The other non-metals are solids at room temperature, including carbon and sulfur.
