82. Reasonable. Got most of the obvious ones, a good number of those named after people, and the systematically named 112-118. Missed a worrying number of transition metals, including Zirconium and Palladium. Should have got Bismuth and Strontium too.
Worst group: Nitrogen's and Oxygen`s (numbering varies and there`s none on the table). Worst period: The lanthanides, naturally.
And Mithril`s not there because it`s not an element, it`s an intermetallic compound probably invloving a lanthanide.
