Answer:
Step-by-step explanation:
Rutherford characterized the atom by delineating a minuscule, compact, and positively charged core known as the nucleus. He determined that the majority of the atom's mass is localized within this nucleus. In Rutherford's planetary model, electrons traverse vacant space around the diminutive, positively charged nucleus, akin to planets orbiting the sun. By directing a stream of alpha particles at gold foil and observing their deflection by gold atoms, he inferred from the outcomes that almost all of an atom's positive charge and mass are concentrated in a minute region, with the remaining space within the atom being largely empty.
