What are Non-metals? Common Properties of Solid Non-metals
Elements described as the solid Non-metals have low melting
points compared to the metals. They are poor conductors of
heat and electricity, they are brittle solids, not ductile
in their solid state - they cannot be rolled into wires or
pounded into sheets. They are usually dull and therefore
show no metallic luster and they do not reflect light. They
also have a low density.
Common properties of Solid Non-metals
The elements classed as solid Non-metals therefore have some
of the following
properties in common:
no metallic luster
Non-metals List - Chemical Elements in the Periodic Table
The elements contained in
the classification of Non-metals list are as follows:
Elements classified as Non-metals
The 7 elements classified as "Non-metals" are located in Groups
14,15 and 16 of the Periodic Table. Solid Non-metals are not easily able
to conduct electricity or heat and do not reflect light.
Non-metallic elements are very brittle, and cannot be rolled into
wires or pounded into sheets. Non-metallic elements exist, at room
temperature, in two of the three states of matter : gases (such as
oxygen) and solids (such as carbon).
