b. the neutrons do not affect the mass or stability of an atom's nucleus, but they are involved in most interactions between two atoms.

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.

Which of the following is a property of an acid solution? a. slippery to the touch b. ph less than 7 c. turns red litmus paper blue d. bitter taste
