1. Why is it that Carbon (C+4 or C-4) cannot form bonds with elements like Potassium (K+) to form (CK4), but Carbide (C2-2) can: (C2K2)? What is the chemical explanation for this? They are both balanced, but one is almost (if not) impossible to create while the other is relatively easy? 2. What's the difference between Potassium (K+) and Hydrogen (H+)? Potassium cannot bond with Carbon to form (CK4) but Hydrogen can bond with Carbon, to form (CH4)? 3. Lastly, what is the explanation for Carbonide (C2-2) being able to bond with Nitrogen (N-3) to form Cyanogen? (C2N2)? Theoretically speaking, shouldn't that be an ion? i.e. ((C2N2)-8), since N2 is -6 and Carbonide is -2?
