so, I'm guessing you spell scalawag with a double "L"

7. scallawag = SC(scandium)AL(aluminium)LA(lanthanum)W(tungsten)AG(silver)

That's a hit, Joan!

Why did I think this one was finished? The answer to #9 is Ha/ir/li/ne, but I'm pretty sure you all know that already.

I made this puzzle in 2004. I have the printout of the list of the element abbreviations I used. Ha is definitely on it. I had no idea it had been changed to Db.
