Gamma rays are neutral particles and do not carry an electric charge. Therefore, they are not affected by electric fields and are not deflected when passing between charged plates. Only charged particles are influenced by electric fields.

How did Rutherford know the nucleus was positively charged?
Rutherford conducted the famous gold foil experiment, where he observed that some alpha particles were deflected back at large angles when they passed through thin gold foil. This led him to propose that the positive charge of an atom is concentrated in a small, dense region called the nucleus.
The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil?
Most alpha particles passed straight through the foil, suggesting that atoms are mostly empty space. Some alpha particles were deflected at small angles, indicating the presence of a small, dense nucleus. A few were even reflected back, showing that the nucleus is positively charged.
Which observations helped Rutherford determine that atoms have tiny dense positively charged nuclei?
Rutherford's gold foil experiment showed that most alpha particles passed through the foil, but some were deflected at large angles, indicating a concentrated positive charge in a small region. Additionally, the discovery of the atomic nucleus was supported by the scattering of alpha particles, which led to the conclusion that atoms have a small, dense, positively charged nucleus at their center.
How do we know atoms are made up of small dense positive nucleus?
Experiments such as the gold foil experiment conducted by Ernest Rutherford showed that atoms have a small, dense, positively charged nucleus at their center by observing how alpha particles interacted with gold atoms. The majority of alpha particles passed through the gold foil, but some were deflected, indicating a concentrated positive charge at the center of the atom. This supported the model of the atom having a nucleus containing protons and neutrons, surrounded by electrons.
What Rutherford discover in his gold foil experiment?
He found that the atom was made up of mostly empty space.
Is it true that a Beta particles when passed through a pair of electrically charged plates will be deflected towards the positively charged plate.?
Yes, beta particles, which are high-speed electrons, will be deflected towards the positively charged plate when passing through a pair of electrically charged plates due to their negative charge and the force exerted by the electric field. This deflection occurs because of the interaction between the electric field and the charged particle.
What type of ray is not affected when it passed through a pair electrically charged plates?
Gamma Ray
Who discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
In Rutherfords gold foil exepirement Rutherford concluded that the atom is mostly empty space with a small massive positivley charged center because?
some alpha particles fired at the gold foil were deflected at large angles, indicating a small, dense, positively charged center (nucleus) in the atom. Most of the alpha particles passed through the foil without being deflected, suggesting that the atom is mostly empty space. This led to the conclusion that an atom is composed of a small nucleus surrounded by a vast region of empty space where electrons orbit.
What was the fate of the vast majority of alpha particles in rutherford's gold-foil experiment?
The vast majority of alpha particles passed through the gold foil without being deflected, as the atom is mostly empty space. However, a small fraction of alpha particles were deflected at large angles, indicating the presence of a dense, positively charged nucleus in the atom.
How Geiger and marsden experiment of alpha was deflected?
In the Geiger and Marsden experiment, alpha particles were fired at a thin gold foil. They observed that while most alpha particles passed straight through, some were deflected at large angles and even back towards the source. This led to the conclusion that the majority of the atom's mass is concentrated in a small, positively charged nucleus, causing the deflections.
How did the gold foil experiment prove an atom was mostly empty space?
In the gold foil experiment by Rutherford, most alpha particles passed through the gold foil, indicating that atoms are mostly empty space. The few particles that were deflected showed that the positive charge of the atom is concentrated in a small, dense nucleus, which explains why most of the particles passed through without being deflected.
What is the explanation for the scattering experiment of Rutherford?
Rutherford's scattering experiment involved firing alpha particles at a thin gold foil. Most alpha particles passed through undeflected, but some were deflected at large angles, and a few even bounced directly back. This led to the conclusion that atoms have a small, dense nucleus at their center, with the rest of the atom being mostly empty space.
What experiment convinced ernest ratherford that the atom has a smallpositively charged nucleus?
The Rutherford gold foil experiment convinced Ernest Rutherford that atoms have a small positively charged nucleus. In this experiment, a beam of alpha particles was directed at a thin gold foil. Most of the alpha particles passed through the foil, but some were deflected at large angles, showing that the positive charge of the atom is concentrated in a small region (the nucleus) within the atom.
What scientists discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, indicating a small, positively charged nucleus at the center of an atom.
What happened to the alpha particles as they hit he gold foil?
When alpha particles hit the gold foil in the famous Rutherford experiment, most of them passed straight through, while a few were deflected at large angles, indicating that the atom was mostly empty space with a dense positively charged nucleus. This unexpected result led to the discovery of the atomic nucleus.
In rutherfords gold foil experiment he concluded that the atom is mostly empty space with a small massive positively chargeed centrer because?
most of the alpha particles passed through the gold foil undeflected or with slight deflection, suggesting that the atom is mostly made up of empty space. The few alpha particles that were deflected back indicated the presence of a small, dense, positively charged nucleus at the center of the atom.
