This question already has an answer here:

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?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ 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
