Answer
Atomic nucleus
Reason — Rutherford through an experiment, directed a stream of α-particles towards a very thin gold foil. Most of the α-particles passed through the metal foil without deviating from their path. Very few (nearly one in ten thousand) alpha particles were either deflected by very large angles or completely bounced back. This suggested the presence of a positively charged mass at the centre of the atom, known as the nucleus.
