9.1, 9.2 Properties of Metals, Reactivity Series

Metals	Non-Metals
Lustrous	D__
Dense	Less dense
M__ & ductile	Not malleable/ductile
High tensile strength	Low tensile strength
High m.p. & b.p. (str. metallic bonds)	Low m.p. & b.p. (weak i__ bonds)
Good conductors of heat & electricity	Poor conductors

Physical Properties

dull, malleable, intermolecular

Metals	Non-Metals
Form __ve ions	Form __ve ions
Metals oxides normally b__	Non-metal oxides normally a__
Can react w/ acid → salt + H2	Don’t react w/ acid to form salts

Chemical Properties

+, -, basic, acidic

Examples of Alloys

Alloy	Mixture of?
Brass	C__ & z__
Steel	I__ & c__

copper zinc, iron carbon

Ø  Alloys have atoms of d__ sizes = distorts r__ arr. of atoms
= ↑difficulty for layers to s__ over each other
= harder & stronger & more useful than pure metal

diff, regular, slide
