Concept:Rutherford's nuclear model describes a tiny central nucleus, with most of the atom being empty space.
Explanation:Rutherford's
α-particle scattering experiment led to the conclusion that an atom has a very small, dense, positively charged nucleus.
This nucleus contains protons and neutrons and accounts for nearly all the mass of the atom.
Because it is massive and positively charged, it can deflect a few of the incoming projectiles.
However, the nucleus occupies only a tiny volume compared with the whole atom.
Most of the atom is empty space, so close to
98% of projectiles pass through undeflected.
Option D describes a region that is very large and also contains the undeflected projectiles.
That description fits the empty space of the atom, not the tiny nuclear region.
Rutherford's account states that the nucleus is extremely small, not very large.
Therefore, option D does not match Rutherford's nuclear theory.
Answer:D. which is very large and in which close to
98% of projectiles pass undeflected.
