Cant seem to figure this one out...

Ta is [Xe] 4f14 5d3 6s2. It's fairly obvious that to make the Na salt the two 6s electrons are removed to make the 2Na^+ + TaF7^-2. I suspect, but I have not been able to confirm it, that what is left is [Xe] 4f14 5d3 6s0 for Ta with the F atoms doing their thing.
