Ionic Bonds
Hi! During lecture 15, Dr. Lavelle explained that all ionic bonds have some covalent character. An example of this that he used was Na+Cl-, and specifically how the anion's electrons were pulled into the bonding region, and therefore this molecule has some covalent bond character. Conceptually I am still confused about why this is. Can covalent bonds also have some ionic character? If anyone could explain this I would really appreciate it. Thank you!

Re: Ionic Bonds
I think this is because if you have a bond between any two atoms, assuming they are different elements, they will have different electronegativities. This means that in all cases besides bonds between two atoms electrons will be somewhat unevenly distributed, as the higher electronegative atom will have more pull over the electrons than the less electronegative atom. This is why most bonds could be described as having some ionic character, as the electrons aren't perfectly shared between both atoms.

Re: Ionic Bonds
I think it is because electrons aren't equally shared because of the differences in electronegativity. So, certain molecules can have different levels of ionic and covalent character.

Re: Ionic Bonds
Because not all elements have the same electronegativity, when bonded together the molecules can have different ionic and covalent character.
