In his gold foil experiment, Ernest Rutherford directed a beam of positively charged alpha particles at a thin sheet of gold and observed that a tiny fraction deflected at very large angles. What primary conclusion about atomic structure did Rutherford deduce from this observation?

A) Electrons are arranged in fixed, quantized circular energy levels around the center.

B) The positive charge and most of the atom's mass are concentrated in a tiny, dense central region called the nucleus.

C) An atom consists of a uniform sphere of positive charge with electrons embedded evenly throughout it.

D) Neutrons and protons have nearly identical masses and are bound together by the strong nuclear force.
