Rutherford Tracked The Motion Of Tiny, Positively Charged Particles Shot Through A Thin Sheet Of Gold Foil. Some Particles Traveled In A Straight Line And Some Were Deflected At Different Angles. Which Statement Best Describes What Rutherford Concluded Fr? ›

Some particles traveled in a straight line and some were deflected at different angles. Which statement best describes what Rutherford concluded from the motion of the particles? Some particles traveled through empty spaces between atoms and some particles were deflected by electrons.

Rutherford's conclusions from the experiment were that atoms must be mostly empty space, and that the positive charge is concentrated in a nucleus.

What did Rutherford determine about the structure of the atom from his gold-foil experiment? Rutherford found that positively charged particles as well as the majority of an atom's mass were concentrated in a quite small volume and the nucleus of an atom is surrounded by negatively charged electrons.

However, due to the positively charged protons which are located in the nucleus at the center of the atom, a very small percentage (about 1 in 8000 particles) bounced off the gold foil at very large angles. Some were even redirected back toward the source.

In Rutherford's gold foil atoms, the gold foils are bombarded with α-particles (He2+). Most of the α particles pass through the gold foil without any appreciable deflection because of a lot of intra-atomic "free space". A small fraction passes near the gold atoms and gets deflected by large angles.

Conclusions are drawn by Rutherford from his α-ray scattering experiment: α-particles passed through the gold foil without any deflection concluding the empty space inside the atom. Deflection is observed in a few particles which proves the positive charge of the atom occupies very little space.

In this Rutherford used fast moving alpha particles as the projectile, to bombard the gold foil. According to his experiment, Rutherford conclusion given below, Rutherford's first conclusion is that the nucleus is smaller than the atom and second is that inside the atom electrons and nucleus are present.

Rutherford's gold foil experiment told scientists that positively charged particles (which Rutherford termed protons) are concentrated in the center of the atom, atoms are largely composed of empty space, and electrons are found in the mostly empty space surrounding the center of the atom (which he termed nucleus).

Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer of metal. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a gold foil in his alpha scattering experiment.

Ernest Rutherford's most famous experiment is the gold foil experiment. A beam of alpha particles was aimed at a piece of gold foil. Most alpha particles passed through the foil, but a few were scattered backward. This showed that most of the atom is empty space surrounding a tiny nucleus.

What did Rutherford determine that blank particles are located in a very small dense region of the atom called the blank? ›

He concluded that all of the positive charge and the majority of the mass of the atom must be concentrated in a very small space in the atom's interior, which he called the nucleus. The nucleus is the tiny, dense, central core of the atom and is composed of protons and neutrons.

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.

The observation that most alpha particles passed straight through the gold foil led Rutherford to conclude that the positive charge in an atom is concentrated in a very small area that is called nucleus. Atoms have mostly empty space.

Originally Rutherford thought that the particles would fly straight through the foil. However, he found that the particles path would be shifted or deflected when passing through the foil. This is due to the fact that like charges repel each other.

Hint: Rutherford carried an experiment using alpha particles. Alpha particles consist of two protons and two neutrons so they are positively charged. Some of the alpha particles deflected since the like charges repel.

In contrast, the particles that were highly deflected must have experienced a tremendously powerful force within the atom. He concluded that all of the positive charge and the majority of the mass of the atom must be concentrated in a very small space in the atom's interior, which he called the nucleus.

The results of the experiments surprised Rutherford because some of the positively charged particles that were shot into the thin gold foil didn't hit the screen. Instead, they were deflected at different angles.

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.
