# Cation and anion bond [closed]

I'm new to chemistry still in a sense - I'm doing AP chemistry and the stuff we learnt in school left a lot of gaps that would have made understanding and grasping the concepts much easer if they had taught us some of the concepts you only learn if you wish to pursue chemistry further

My question is as follows and I know its such a stupid question from a AP chem student but yeah :

Is there a chemical bond or compound that can make a cation and anion of the element. I'm just going to use random elements to make my point without taking into consideration of valency and electrons for the sake of asking the question. Say we bond Ca with Br (that should be a easy bond with Br2 if I recall the properties) and now we have a cation of Ca and a anion of Br - now hypothetically we bonded another ion of Ca but the math's works out to show we have 1 Ca cation 1 Br anion and 1 Ca anion... I know that cant work out with these elements but hypothetically speaking my question is basically is there a way in a bond to have a cation and anion of the same element X as a result of the reaction with the other element Y - once again to simply what I'm asking to not appear that silly is basically 1X+ : 1X- : 1Y+ (X being the same element and Y being a different) is that possible?

Thanks - any feedback that educates me further will be appreciated ;)

• Like the only way to form simple cations and anions with positive and negative oxidation state side by side are ionization processes in gaseous or plasmatic phase. But there is no mutual ionic bonding, like $$\ce{O2+}$$ + $$\ce{O2-}$$
• The elements with positive oxidation state in both cases form complex anions with oxygen ( $$\ce{Mn^2+}$$ + $$\ce{MnO4-}$$ or halogens ( $$\ce{Cu^2+}$$ + $$\ce{CuCl4^2-}$$ ) or negatively charged ligands ( $$\ce{Fe^3+}$$ + $$\ce{[Fe(CN)6^3-}$$ )
• Alkali metals can form in very special environments alkalides. But it is not a simple ionic compound like e.g. $$\ce{Na+ Na-}$$. The cation must be stabilized by suitable complex agent, like 2,2,2-cryptand or 18-crown-6 ether.
