Just a guess... Leland -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of David D. Hillman Sent: Friday, June 11, 2010 12:14 PM To: [log in to unmask] Subject: [TN] NTC Friday Element Quiz - the Question Hi folks - ok, Bev pointed out that I was not fulfilling my duty and had not posted a Friday Element Quiz - here ya go: The Question This element is naturally occurring and was first discovered in 1902. The chemical behavior of this element is nearly identical to the element La. This element is a weak beta emitter. Producing this element is very challenging and one of the easier production methods is to produce it synthetically by neutron bombardment of Ra isotopes in fission reactors. Who am I? Good Luck - this should be a difficult element to identify.
