Gamma rays are photons (light particles). Photons are particles with no mass, no charge and no magnetic moment. Hence they cannot be affected by either an electric or a magnetic field.

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?

A+ answer: A few of the alpha particles in his expeirment were deflected from the gold foil at large angles. Scattering pattern of alpha particles 'shot' at a thin gold foil. Most went straight thru showing the nucleus was very small. Analysis of the scattering showed electrical repulsion, not that the particles actually hit the nucleus and bounced off.


How do we know atoms are made up of small dense positive nucleus?

The first ever experiment this fact was the alpha particle experiment which was conducted by Rutherford. In this experiment, alpha particles are positive charged substances and they were repulsed with the nuclei in the golden foil.


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?

In Rutherford's gold foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positively charged center because most of the electrons passed through but a few were wildly deflected.


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 conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.


How did he know that the nucleus was positively charge?

Ernest Rutherford inferred that the nucleus was positively charged through his famous gold foil experiment in 1909. When he bombarded a thin sheet of gold with alpha particles, most passed through, but a small fraction were deflected at large angles. This unexpected deflection indicated that a dense, positively charged center (the nucleus) was present within the atom, repelling the positively charged alpha particles. This led to the conclusion that the nucleus must contain a positive charge to account for the observed scattering.


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.
