Flourine is the most electronegative element .... hence it does not lose an electron easily.... It has 7 electrons in the outer most orbit.. It is the smallest size atom too. So it does not lose electrons easily.
Na , has one valence electron, Magnesium has 2, and Aluminum has 3.. These are metals which lose electrons easily..
