Q. I have a question regarding bonding. A. Electronegativity is the attraction of an atom for electrons. The difference in the affinity for electrons determines the type of bond that can form. This is a non-polar bond and is found in molecules that are symmetrical. The hydrogens are slightly electropositive and the oxygen is electronegative.
Water is a polar molecule.
Q. I was looking over the Self Quiz in Chapter 2, and I think the answer for the first question is wrong. The question claims that the electron carries a positive charge. The answer in the textbook is wrong. Give an example of homeostasis in the human body. Both names appear either in italics or are underlined.
