1.

In an ionic solid, the ions are arranged to

maximise repulsions
be random
form molecules
maximise attractions and minimise repulsions
2.

Ionic solids are brittle because

ions are weakly held
they have delocalised electrons
they are molecular
shifting layers brings like charges together, causing repulsion
3.

Ionic solids conduct electricity

as solids
never
when molten or dissolved, as ions are mobile
only when cold
4.

Metals are malleable because

they are brittle
the sea of electrons allows cations to slide without breaking bonds
ions repel
they are covalent
5.

An interstitial alloy forms when

small atoms fit into the spaces between larger metal atoms
atoms of similar size replace each other
metals react to form a compound
a metal melts
6.

A substitutional alloy forms when

atoms of similar radius replace some host atoms
small atoms fill holes
ions form
electrons are removed
7.

Interstitial alloys are generally

softer
more ductile
non-conducting
harder and less malleable than the pure metal
8.

Metals conduct electricity because

ions move
they contain molecules
they are ionic
valence electrons are delocalised and mobile
9.

Ionic solids generally have

low melting points
high vapour pressure
high malleability
high melting points
10.

Alloys usually retain

electrical conductivity because electrons are still delocalised
no metallic properties
ionic bonding
covalent networks
