Why are some molecules electrically neutral, whereas others display polarity?
a. Molecules that have lost an electron will have a positive charge. b. All molecules start off electrically charged, but this charge weakens over time. c. Relative differences in electronegativity between elements in a molecule result in negatively charged electrons spending more time near some elements than others, resulting in asymmetrical charge distributions. d. Radioisotopes eject positrons as they decay, becoming more electrically negative over time.
