Key Concepts

Empty Space in Atoms

This concept describes that most of an atom's volume is comprised of empty space. In Rutherford's model, this explains why the majority of incident alpha particles pass through the thin foil without any noticeable deflection, as they do not come close enough to the tiny, positively charged nucleus.

Coulombic Repulsion

This concept involves the electrostatic force between similarly charged particles. In the context of Rutherford’s model, it explains that alpha particles are deflected when they come near the nucleus due to the repulsive force between the positive charges of the nucleus and the alpha particles, which causes some particles to scatter backward.

Atomic Nucleus

This is the concept that atoms possess a concentrated, dense core of positive charge, which accounts for nearly all of the atom’s mass. It explains the scattering of some charged particles: when an alpha particle approaches this small, yet highly charged region, it experiences a strong Coulombic repulsion that can deflect it significantly.
