What is electron pair repulsion theory?
electrons are all negitivly charged, so the clouds will repel each other as much as they can lone pairs repel most, then lone and bonding, lastly bonding and bonding.

How to calculate number of electron pairs.
find the central atom, find number of electrons in the outershell, add number of bonds, divide by 2.
