Elements that have higher electronegativity difference are ionic and those that have less electronegativity difference are covalentCan this statement be used in deciding which compounds are covalent and ionic in general?What about the fact that all bonds formed by an element are covalent if the element has small size, high charge denisty, i.e high polarising power in the case of cations, like boron shows high covalent characteristic?Can someone clear it up for me by giving me deciding factors on cations/anions which are ionic or covalent?
