    • B. 

      The number of neutrons

    • C. 

      The number of protons

  • 10. 
    • A. 

      In the atomic nucleus

    • B. 

      Outside the nucleus, yet very near it because they are attracted to the protons

    • C. 

      Outside the nucleus and often far from it - most of an atom's volume is its electron cloud

    • D. 

      Either in the nucleus or around it - electrons are readily found anywhere in an atom
