Electric current is a
flow of electrons or ions
1) when elections or ians more ,
they cause the
material toConduct
they're in electricity
2) Fanic
compounds only conduct
electricity when
molten .
3) covalent don't have
able any charged particles that are
to move , conduct electricity
so
they can't .
Metals held
together by metallic banding
are
1) metals have a
giant structure of positive ins
surrounded by a sea of delocalised electrons
.
2) the nuclei
electrostatic attractions between the
of positive ions and electrons called
the is
metallic banding.
3) this metallic banding gives metals their
properties
