Hi folks - It appears that everyone is really overloaded with work, having too much fun with the holidays or I made the Friday Element Quiz too hard last week so here is an additional clue: The Question: This element has a world inventory supply of nearly 1 gram. This element is the heaviest element that has engineering use. This element melts at 900C and boils at 1470C. Bonus question: This element has two crystal structures - name the crystal structure that exists above 590C.
