Do the alpha particles in Rutherford's experiment contain electrons?
No, alpha particles are helium nuclei made up of two protons and two neutrons, with no electrons. In Rutherford's experiment, alpha particles were used to probe the structure of atoms by scattering off the positive nucleus, helping to reveal the atom's structure.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
Why did Rutherford use alpha particles rather than electrons for his scattering experenment?
Rutherford used alpha particles because they have more mass and positive charge compared to electrons, making them more suitable for studying the size and charge distribution of the atomic nucleus. The greater mass of alpha particles led to less deflection when they interacted with atoms, allowing Rutherford to better understand the structure of the atom by observing the scattering patterns.
What correctly describes the charge of beta particles and alpha particles?
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
How did Rutherford explain the fact that some of the alpha particles bounced sharply back off the gold foil?
Rutherford explained the sharp bounce of some alpha particles off the gold foil by proposing that atoms have a dense, positively charged nucleus at their center. Most of the alpha particles passed through the foil because the majority of an atom is empty space, but those that were deflected at large angles encountered this concentrated mass of positive charge, which repelled the alpha particles due to electrostatic forces. This led him to conclude that the atom's structure is mostly empty space with a small, dense nucleus, fundamentally changing the understanding of atomic structure.
Alpha particles led to what discovery of what?
discovery of the atom's structure

Does radioactive mean in science?
The atoms structure is unstable and it emits alpha or beta particles that changes the Atom
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.

What is the type of radioactive decay in which positive particles are given off?
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.
What correctly describes the charge of beta particles and alpha particles?
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
What did Rutherford say about the small number of particles that bounced straight back?
Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.
What was the purpose of the fluorescent screen in rutherfords experiment?
The purpose of the fluorescent screen in Rutherford's experiment was to detect the alpha particles that were deflected when they struck the gold foil. The screen would light up when hit by the alpha particles, allowing Rutherford to observe and measure the deflection pattern and infer the structure of the atom.
