Fluorine, with the chemical formula F2, is a pale yellow-colored diatomic gas, which has a pungent odor. F2 has a molecular weight of It is toxic in nature; it can cause chemical burns on the skin and can be lethal if inhaled. It is highly reactive, is capable of corroding metals, and is unstable at high temperatures. Industrially, F2 is generated via electrolysis of molten potassium bifluoride KHF2 at high temperatures; fluorine gas is liberated at the anode, whereas hydrogen gas is liberated at the cathode. Fluorine is majorly used to prepared the uranium fluoride required for the nuclear fuel cycle.

A Lewis structure is a way to show how atoms share electrons when they form a molecule. Lewis structures show all of the valence electrons in an atom or molecule. The valence electrons are the electrons in the outermost shell. For representative elements, the number of valence electrons equals the group number on the periodic table. To draw the Lewis structure of an atom, write the symbol of the atom and draw dots around it to represent the valence electrons. Note that hydrogen is often shown in both group 1A and group 7A, but it has one valence electron — never seven.
