Giant ionic lattice
huge 3D regular structure held together by the electrostatic forces of attraction between positive and negative ions
Melting and boiling points of ionic substances
high
Reason for melting and boiling points of ionic substances
Strong electrostatic forces between opposite ions need lots of energy to break
Movement of ions in a solid
Ions vibrate around fixed positions
Molten
Made liquid by heat
Movement of ions when molten
Ions can move past each other
Movement of ions in solution
Ions break apart and move freely
Conductivity of solid ionic compounds
don't conduct
Reason for conductivity of solid ionic compounds
Ions are fixed in place
Conductivity of molten/dissolved ionic compounds
good conductors
Reason for conductivity of liquid/dissolved ionic compounds
Ions are free to move and carry charge
Electrostatic force of attraction
attractive force between oppositely charged particles
