Who identified cathode rays as subatomic particles?
Experiments with cathode rays led to the discovery of the electron.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
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.
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.''
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.

Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
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
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
Alpha particles and beta particles differ in?
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
In what decade did scientists first split the atom?
British Physicist Ernest Rutherford is considered the 'father of nuclear physics' and is credited with splitting the first atom in 1917. He pioneered the Rutherford model of the atom and theorized that the charge of an atom is concentrated into a nucleus. He was able to split the atom in a nuclear reaction between alpha and nitrogen particles which led to the discovery of the proton.
