MetalsMetals

Capable of reflecting light (luster).

Good conductors of heat and electricity. [http://www.bsieducation.org/Education/14-19/topic-

MetalsMetalsPure metals

are held together by metallic bonding.

Electrons can travel “between” the atoms.

Malleable – can be hammered or rolled into sheets.

Ductile – can be made into wires.

Alkali MetalsAlkali MetalsAre very “soft”

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.
