MetalsMetalsPure metals
are held together by metallic bonding.
Electrons can travel “between” the atoms.

and have low density and melting points
Usually form compounds with group 17.

Alkaline Earth MetalsAlkaline Earth Metals
All have 2 valence electrons.
Can exist as pure elements, because they are less reactive than alkali metals.

Transition MetalsTransition Metals
Many transition metals are made into alloys in order to combine their properties.
Metals are melted then mixed together.

The purity of gold is determined by the different ratios of gold,
copper, and silver present.
