explain how the electron pair repulsion theory can be used to deduce the shape of, and the bond angle, in PF3

1) State the number of bonding electrons/lone pair
2)say that electrons = negative charge, and these will repel other pairs of electrons to an area of minimum repulsion
3) if there are all bonding pairs, say they all repel the same amount
4) if there are for example one lone pair and 3 bonding, then state that the lone pair repels the bonding pairs of electrons more greatly.( Lone pair electrons repel more than bonding pairs)
5) i think to round it off it would be good to wack in the bond angle and the shape
safe
