Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n 2) electrons.
F- has the smallest radius. It has ten electrons, so only the first two 'shells' are filled. The others have electrons in the third 'shell', which is at a greater distance from the nucleus. Sice flourine is in the lowest energy level so it has the lowest radius. fluorine. it comes first in the periodic table out of all of them. so its nucleus has the least amount of protons and neutrons - which have much more mass than any electrons.
