Verified step by step guidance1
Identify the position of fluorine in the periodic table. Fluorine is in Group 17, which is the halogen group.
Recall that elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons.
Look at the options and determine which element is also in Group 17. Chlorine is in Group 17, while oxygen is in Group 16, nitrogen in Group 15, and neon in Group 18.
Since chlorine is in the same group as fluorine, it will have chemical properties most similar to fluorine due to having seven valence electrons and similar reactivity patterns.
Therefore, the element with chemical properties most similar to fluorine is chlorine.
