# Why is the repulsion between lone pairs and bonded pairs stronger than the repulsion between the bonding pairs and the bonding pairs? [duplicate]

My book says "The reason for this difference is that the electron pair in a bond is further from the nucleus of the central atom than the electron pair in a lone pair."

I don't get it , how does the distance make any difference ? I'm , taking AS level chemistry

From Coulomb's law Wikipedia $$\pu{ F \propto \frac{1}{r^2} }$$ If your electrons are closer to the center then the distance between them is small.
