I'd say sulfur...

Explanation:

Selenium #(Se)# and sulfur #(S)# both belong in the same group, which is the #16#th group or the chalcogens group. Bromine is in the #17#th group or the halogens group.

Elements that are in the same group on the periodic table have similar characteristics and usually have a trend with their melting point, boiling point, reactivity, etc. They also have the same number of valence electrons.

Can you think of any other elements that have something in common with selenium?
