Ionic Bonding

• Always occurs between metals (group 1 and 2) and non metals (group 6 and 7)
• Involves electron transfer from the metal to the non-metal
• Always produces charged ions
• Positive ions are called cations
• Negative ions are called anions
• Ionic bonded molecules form a giant three dimensional lattice of ions which are strongly attracted to each other due to opposite charges on the ions. There is also repulsion between ions of the same charge
• The forces between these ions are very strong electrostatic forces
