Molten sodium chloride is broken down in an electrolytic cell into the elements sodium and chlorine. Where do the products form?
O Sodium forms at the cathode through oxidation, and chlorine forms at the anode through reduction.

explanation:

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
