ionic bonding model
strong electrostatic forces between cations and anions in fixed positions in the 3D crystal lattice
Properties
high mp and bp, brittle, hard, no electricity conducting in solid, can conduct in liquid
strong or weak?
strong
solid state
no free moving particles, cannot conduct electricity
liquid state
free moving particles, can conduct electricity
high mp and bp
strong electrostatic forces between positively and negatively charged ions, requiring a lot of energy to break
hard
strong forces, so a strong force is required to disrupt them.
brittle
when hit, ions move within the lattice and repel each other, causing them to break
