Selen....

und jetzt mit Begründung:
In inorganic chemistry, selenium is known as red amorphous powder or as grey metal, in biology it is either a toxin or an essential trace element, in oncology it acts one on hand as a carcinogenic but on the other hand also as a cancer prophylactic, in supermarkets and drug stores it is sold as “Antioxidant”, in toxicology it is the initiator of radical chain reactions, in biochemistry it is a catalytically active atom making part of the active site of enzymes, which break radical chain reactions. Such poly-ambivalent behavior is called moonlighting. Looking at this, one might ask whether Berzelius in 1817 anticipated all these properties when he named his newly discovered element after Selene, the greek goddess of the moon.
