C2- Structure and Bonding

Ionic Bonding 

• A metal reacts with a non-metal, metal atom loses electrons and becomes a positive ion, the non-metal atom gains electrons and becomes a negative ion.
• The oppositely charges ions are electrostatically attratced, this is ionic bonding.

• Lithium loses 1 electron to be stable 
• Metal- ions stay the same
• Fluorine gains 1 electron to be stable 
• Non-Metal- ions change: fluorine-->fluoride, oxygen-->oxide

• Ionic compounds can conduct electricity, only if the ions are free to…
