    The atomic number of an atom is:
    • A. 

      Its number of protons

    • B. 

      Its number of electrons

    • C. 

      Its number of neutrons

    • D. 

      Its number of ions

    According to atomic theory, electrons are usually found:
    • A. 

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

    • B. 

      In the nucleus of the atom

    • C. 

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

    • D. 

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

      Neutrons and Protons, because of electrostatic attraction

    • B. 

      Protons and Electrons, because of electrostatic attraction

    • C. 

      Neutrons and Protons, because of electronegativity and the attraction of protons

    • D. 

      Protons and Electrons, because of electronegativity and the attraction of electrons
