• All the elements of the same column or group as Fluorine have the same number of valence electrons.
• Thus, all the elements in the column have $7$ valence electrons.
• The valency of all elements in the same group of the periodic table as fluorine will be $1$.
• All the elements in the group are non-metals as fluorine.
• All the elements in the group are highly electronegative.
