What is ionic bonding
strong electrostatic forces between cations and anions in fixed positions in a 3D crystal lattice
Properties
High Mp/Bp: strong forces between cations and anions that require a lot of energy to break
brittle: when hit, ions move within lattice and repel each other, causing them to break
hard: Strong forces therefore, strong gorces required to disrupt
Can ionic bonded elements conduct electricity
No in solid state, yes in liquid as the ions are free to move
Cations
+ve,
Anions
-ve
