# F ion has smaller size than F atom

$(a)\;\text {True} \\(b)\;\text {False} \\ (c)\;\text{Don't know} \\ (d)\;\text {wrong statement}$

F ion has smaller size than F atom is true.
The addition of an electron in Fluorine atom makes it fluoride ion so no of electrons are higher than protons , the extra electron produces repulsive force in outermost shell and electrons move away from nucleus and hence radius of electronic cloud is larger than fluorine atom.
Hence a is the correct answer.
