Alloys

have some properties that are better.

Metallic bonds

draw positively charged ions to their free floating electrons.

Octet rule

completely filled valence electrons - Noble gasses have filled valence electrons and are stable

\

Anionions

when an atoms gains electrons.

Copper

is most abundant being 88 % of bronze.

Dot structure

represents valence electrons as a dot.

Metals

lose electrons. Cations. +sign/charge

Anionions

when an atoms gains electrons

Sea of electrons

when the valence electrons are mobile and can drift freely and part of the metal to another
