How did the results of Rutherfords gold foil experiment differ from his expectations?
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.
What is the difference between particle size and crystallite size?
crystallite is the average size of the particle whereas the particle size denotes the individual size of the particle.
Which has the largest mass alpha particle gamma ray positron or beta particle?
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
A heavier nuclear particle is composed of a triplet of strange quarks. What is a charge if this particle?
electron particle
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
What caused the deflection of the alpha particles in Rutherfords gold foil experiment?
A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
What would happen to the deflection of the cathode ray if the particle in the rays were heavier?
deflect more
What describes Rutherfords model of an atom?
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
Explain why diffusion is evidence for particle models?
Diffusion is evidence for particle models because it causes diffusions

How can you prove that light is a particle?
The photoelectric effect was pretty definitive evidence that light is a particle (well, at least sometimes a particle).
Can you give me an example of declarative sentence using the word 'particle'?
The explanation was disappointing, not a particle of supporting evidence
Who discovered evidence of positively charged particle?
It's goldstein.
A whitish sky is evidence that the atmosphere contains?
A mixture of particle sizes
Which particle did j.j. Thomson discover?
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
What effect does a magnetic field have on a charged particle?
Yes, a moving electron will create a magnetic field. Any moving charge will create a magnetic field around its path of travel. This is the basis for the electromagnetic force, which is one of the four fundamental forces in nature.
Who provided the evidence that atom contains subatomic particle?
It was J. J. Thomson (Joseph John Thomson)
