Comb and hair, is that an example for ionic boding? As i understand, when brushing hair, some electron transfer from hair to the comb. Thus, make the comb have different charged from hair and they attract each other.
It's look likely what i have learn from school about ionic bond. One electron from Na is transfer to F and so we have NaF . Isn't it ???
No, not at all. It is an example for triboelectric charging. A mechanical example for this type of electrostatic generators would be a Van de Graaff generator. 

But all this has nothing to do with ionic bonds.
