How does Rutherford's model of the atom explain why some of the alpha particles directed at the gold foil were deflected straight back toward the source?
A)Alpha particles sling shot around the atomic nucleus much like comets sling shot around the sun.
B)Each atom has a center in which mass is very dense, but elastic.
C)The gold nucleus is able to deflect alpha particles much like a mirror is able to reflect photons.
D)The atomic nucleus is very small but dense and carries a positive electric charge.

Rutherford's model of the atom proposed that the positive charge in an atom is concentrated in a small, dense nucleus located at the center of the atom. This explains why some of the alpha particles directed at the gold foil were deflected straight back toward the source. If the alpha particle came too close to the positive nucleus, it would be repelled and deflected back.
