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.
How does Alpha particles affects us?
They don't, or at least, the effect is negligible. Alpha particles can be deflected with a sheet of paper.
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not contain electrons.
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Both Beta and alpha particles can be blocked by a block of lead. Alpha particles can even be blocked by a sheet of paper, and beta particles can be blocked by a thin aluminium plate.
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
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 gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''

Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
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.
If the mixture of electrically neutral how many more beta particles than alpha particles are in the balloon?
alpha particles would have twice as many beta particles
Alpha particles are repelled by atomic nuclei because?
Alpha particles are repelled by atomic nuclei because alpha particles have a positive charge, and so do atomic nuclei. The positive charge on the surface of a nucleus will repel another positive charge, like an alpha particle, because of the law of electrostatics. That's the simple answer. And it is correct. But know this: Alpha particles were used in the early investigations of atomic structure and atomic interactions. The alpha particles were used to bombard atomic nuclei, and there are times when an alpha particle will be absorbed by an atomic nucleus. Somehow the laws of electrostatics took the day off, and the fact that absorption took place opens the door to discovery and discussion of other atomic forces. Word up.
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.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
