What else can I help you with?
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.
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
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.

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.
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 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.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
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.
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.
