Which of the following does  notaccurately describe the forces that exist with an atom?                 a.  electrons in an atom are attracted to the protons within the nucleus due to opposite charges.      b.  electrons closer to the nucleus and electrons farther from the nucleus repel due to like charges.      c.  electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away.      d.  electrons positioned farther away from the nucleus are less attracted to the nucleus than are electrons positioned closer to the nucleus.

Which of the following is the result of the nuclear weak force? the instability of large nuclei the repelling force between positively charged protons the structure of the atom certain types of nuclear decay
