I am trying to find the ground state for, Pb2+

I went back two on the chart and came to Hg. And entered it's ground state.

Why is this wrong?

  • Chemistry -

    Are you trying to determine the term symbol? I think Pb^+2 has the same electron configuration as elemental Hg. And elemental Hg has the term symbol below.
