Which atom will form the most polar bond with the greatest degree of ionic bonding when bonding with sodium?

A because fluorine is the most electronegative.

Fluorine, the most electronegative element of all, forms the most ionic bond with sodium. Electornegativity difference for these elements is: F = 3.05, Cl =2.23, Br = 2.03, I = 1.73. All are ionic but the Na-I bond is just barely on the ionic side of the bond spectrum - maybe 53% - 57% ionic.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
