What are the properties of metals?
People use lots of metallic elements in their everyday lives. These include elements like iron, copper, gold and silver.
Most metals share similar properties with each other. For example:
They have high melting and boiling points meaning they are solid at room temperature
They are good conductors of heat and electricity
They are shiny in their appearance
They are malleable
Other common properties of metals are:
They are hard and strong
Have a high density
They are sonorous
What are the properties of non-metals?
What are the properties of non-metals?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements.
Non-metals have properties in common with each other. For example, they are often:
Poor conductors of heat and electricity
Dull in their appearance
Weak and brittle
Some other common properties of non-metals are:
Generally low melting and boiling points, meaning they are gases and liquids at room temperature
Not sonorous
