Answer:

Well selenium is a chalcogen; it shares the same group, and same electronic structure as oxygen or sulfur.

Explanation:

And thus if we got #Cr(VI+)#, we would have #CrSe_3#, just as we have #CrO_3# or #CrS_3#...in that oxygen, sulfur, and selenium commonly form #E^(2-)# ions........

While #CrO_3# is certainly known, #"chromic selenide"# might be rare or unknown. The Cr(II) salt, CrSe, is certainly known........
