Can metal ions be engineered to behave like non-metals in terms of chemical properties (by supplying or removing electrons), would the altered metal ions bond covalently?

Would the ions be too unstable and begin to decay?

  • $\begingroup$ There are quite a lot covalently bound metals to metals already, and I do not understand what you mean with engineering metal ions; Could you exlain a little more? $\endgroup$ – Martin - マーチン May 11 '15 at 10:00
  • $\begingroup$ some examples of these molecules and/or covalent networks would be appreciated. also by 'engineering' i mean creating an ion that behaves in a specific chemical manner due to the number of valence electrons it possesses by removing or adding electrons from the valence shell. $\endgroup$ – ziggy May 11 '15 at 10:22

    $\begingroup$ The most ready answer to this question is $\ce{Hg_2^{2+}}$ and other polycations of mercury. $\endgroup$ – Ben Norris May 11 '15 at 10:33
