The metal elements are found on the left hand side of the periodic table, and the non-metal elements are found on the right. You can imagine a zig-zag line, starting at B-Al-Si, separating metals from non-metals.
The table summarises some typical properties of metals and non-metals.
|High melting points||Low boiling points|
|Good conductors of electricity||Poor conductors of electricity|
|High density||Low density|
Most metals have high melting points and are therefore in the solid state at room temperature.
Most non-metals have low melting points are not in the solid state at room temperature.
Some elements have properties that are not typical. For example:
A substance with a high density means it has a high mass for its volume. Malleable substances can be bent or hammered into shape without shattering, whereas brittle substances shatter when bent or hit.
