All was explained! The dense atomic centers (each later called a "nucleus") of the gold atoms were so small that most of the alpha particles zoom right through as if there was nothing there.

Why would the alpha charge go through the gold foil?

The fact that most alpha particles went straight through the foil is evidence for the atom being mostly empty space. A small number of alpha particles being deflected at large angles suggested that there is a concentration of positive charge in the atom.

Why did many alpha particles pass through the gold foil undeflected?

Answer: a) since most of the space of an atom is empty, many particles pass throgh undeflected.

When alpha particles were shot at gold foil what happened to the alpha particles?

In Rutherford's gold foil experiment, a beam of α particles that was shot at a thin sheet of gold foil. Most of the α particles passed straight through the gold foil, but a small number were deflected slightly, and an even smaller fraction were deflected more than 9 0 ∘ 90^{\circ} 90∘ from their path.

What happened to the alpha particles when they hit the gold foil in experiment?

Most alpha particles passed straight through the gold foil, which implied that atoms are mostly composed of open space. Some alpha particles were deflected slightly, suggesting interactions with other positively charged particles within the atom.

Why do most alpha particles fired through a piece?

Why do most alpha particles fired through a piece of gold foil emerge almost undeflected? The massive alpha particles blast through the majority of the space in the gold that is occupied by low mass electrons. What did Rutherford discover about the atomic nucleus?

Why did the alpha particles bounce back?

Most of the alpha particles passed straight through, but some of the alpha particles bounced back because positive particles (protons) in the nucleus repelled them. Positive and positive always repel each other.

What happened in gold foil experiment?

Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.

Why did Rutherford perform the gold foil experiment?

Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections.

Can alpha particles pass through aluminum foil?

An alpha particle can pass through a thin sheet of aluminum foil, but it is stopped by anything thicker. Beta "rays," a second form of radiation, turned out to be electrons, very light particles with a negative electric charge.
