How could you tell when at atom or molecule is polar or nonpolar?

The concept of polarity does not apply to atoms, it is bonds between atoms that can be more, or less polar. If one atom is significantly more electronegative than the other it attracts a larger share of the electron density making it partially negatively charged, and the other atom then becomes partially positively charged. Electronegativity increases going along a period left to right, and up a group, bottom to top (the most electronegative element is Fluorine).

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.
