Ionic Bonding

Why do atoms form Bonds?

• Atoms with an outer shell of eight electrons have a stable elctronic structure
• Atoms can be made stable by transferring electrons. This is called ionic bonding
• Metal atoms lose electrons to get a stable electronic structure
• If an atom loses electrons, as positive ion is formed
• Non-metal atoms gain electrons to get a stable electronic structure
• If an atom gains electrons, a negative ion is formed
• During atomic bonding, the metal atom becomes a positive ion and the…
