Metals

They are good conductors of sound. They are sonorous.

Metals are ductile which means that they can be used to make thin wires.

They are malleable which means that they can be pounded into thin sheets.

Metals are usually solid at room temperature. However, there is an exception i.e. Mercury which is usually in liquid form.

There are a few metals that have low density, soft, and have low melting and boiling points. These metals are alkali and alkaline earth metals, they are also highly reactive, and are rarely encountered in their elemental, metallic form.

Some metals like sodium are so soft that they can be cut with a knife.

Three magnetic metals are iron, nickel and cobalt. Steel is also magnetic but it is an alloy which contains iron.

Metals tend to gain valence electrons.

Also, metals have low electronegativity.

Metals usually have one to three electrons in their outer shell.



Non metals

Nonmetals have high ionization energies.

They have high electronegativities.

Nonmetals are insulators which means that they’re poor conductors of electricity.

They are dull, they do not have lustre like metals.

Nonmetals are poor conductors of heat. They’re poor thermal conductors.

They are very weak and brittle. They tend to easily break or shatter.

Nonmetals have a low density. They’re light for their size.

They aren’t good conductors of sound and do not make sounds when they are hit.

They tend to gain electrons easily.

Nonmetals maybe solid, liquids or gaseous.

Nonmetals form acidic oxides.

They’re good oxidizing agents.

Generally, Nonmetals have four to eight electrons in the outer shell.
