ELECTRICAL CONDUCTIVITY & METALS
lonic compounds :
only conduct electricity when molten or aqueous
the ions in an ionic compound are able to move when dissolved in a solution
↳ the compound will conduct electricity
made of a lattice of positive and negative ions
solid ionic compounds is don't conduct electricity
·
↳ the ions are unable to move around
Metallic Bonding !
metals have a giant structure of positive ions surrounded by a sea of delocalised electrons
metallic bonding :
the electrostatic attractions between the nuclei of the positives ions and electrons
↳
gives metals their properties
·
metals are congood Shaman
delocalised electrons are able to move through the structure
metals can conduct electricity
↳
energy is also transferred quickly through the material
↳ metals are good conductors of heat
