Sorry guys , I m New at theory etc .... I know scales /chords

but how do you determine which scale goes with which chord ? 

For instance ....

if in key of F major  would you play the scale modes over each chord interval? Help me and this might not make any sense to a lot of you

First of all, the scale of choice has to have all the chord tones. Then, the more tones the scale has together with the acutal key the better.
Sometimes you just try  and let decide your ear.
