The outermost orbit of an atom of an inert gas is saturated by the number of electrons given by the formula $2 n^{2}$ where $n = 1, 2, . . .$ The atom represent by 'F' has its atomic number $18$ that has electronic configuration $2, 8, 8$ . Which shows that its outermost orbit contains $8$ electrons and hence saturated.
