Ionic Bonding

KEY POINTS ABOUT IONIC BONDING:

• Ionic bonding is the transferring of electrons, where an atom will either lose or gain an electron to form a charged particle (ion).
• Ionic compounds aalways have giant ionic lattices.
• They are arrange
• The ions are closely packed together in a regular lattice arrangement
• Strong electrostatic atttraction between oppositely charged ions in all directions.
• High melting points, high boiling points due to strong attraction between the ions - it takes a lot of energy to overcome this attraction.
• When ionic compounds melt, the ions are free to move and they'll carry electric current.

REMEMBER:

• Atoms that have lost or gained an electron (or electrons) are ions!                   
• Ions have the elctronic structure of a noble gas!
