[SiF6]2- exist but [CF6]2- does not, why?

A nice question both silicon and carbon belong to group 14 and have 4 electrons in the outermost shell. Their general valency is 4 , but silicon and other elements show higher oxidation states also. Only carbon is the element in group 14 elements that do not have vacant d-orbital. All other elements like silicon

Why is an ionic bond not double or triple like a covalent bond?

By ankushmaster on May 18, 2020November 21, 2020

To understand this we have to go in depth , that how the ionic bond is formed? Ionic bond is a bond basically formed due to strong electrostatic forces of attraction which is totally different from the covalent bond. Ionic bond is formed between atoms with very different ionisation energy and electron affinity. This situation
