Re-order each list of elements in the table below, if necessary, so that the elements are listed in order of decreasing electronegativity.

F, O, B

O, Se, Te

Explanation:

As you go across the periods, electronegativity increases. As you go down a group, the electronegativity decreases. This means that the elements on the upper right side of the periodic table are the most electronegative elements, and the elements on the left lower side of the periodic table are the least electronegative.
