Model B: In this model the atom is a solid sphere that cannot be divided up into smaller
particles or pieces. The atom is neutral and has no charge. Atoms of the same element are
mad of the same types of atoms.
Model D: In this model the atom is a sphere containing negatively charges particles
embedded in it. These small negative particles were originally called “corpuscles”
and later called electrons. However it was recognized that the atom is neutral (no
charge) so there must be an equal positive charge in the atom to offset the negative
charge of the electrons. Since no other particles were known at this time the rest of
the atom consisted of a positive charge.
It is possible to remove a negatively charged particle from an atom using electrical forces
(Thompson, 1897). Compare models B and D. Which model supports this evidence?

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
