what symbols are used to represent the charges on atoms in a polar covlaent bond? the polarity of the bond?
I am a little confused by the question. I would answer that the polar covalent bond is represented with small delta + and small delta -; however, that leaves no answer for the second part of the question. SO, I would answer the first part as lower case delta sign and the second part of the question as + and -. The polarity of the bond also may be represented with a +-----> where the arrow points to the negative end of the dipole and the + sign is on the positive end.
