Bear with me, I\'m trying to type the Lewis structure: ::O=Se-O::: and there are four electrons surrounding the selenium. So: Oxygen with four unpaired electrons and a double bond to Selenium. Selenium with four unpaired electrons bonded by a single bond to Oxygen with six unpaired electrons. Hope I helped!
