Question

How would `TcI_2` behave in water?

Answer 1

`TcI_2(s) + nH_2O rarr [Tc(OH_2)_n]^(2+)(aq) + 2I^(-)(aq)`

Explanation:

I am guessing that `Tc(II)` has an equivalent coordination chemistry to `Mn^(2+)`. All isotopes of `Tc` are unstable, and as a result, its chemistry is very under-developed. The very name `"technetium"` means made by the hand.
