Alpha particles and beta particles have
different properties, the alpha particles are helium nucleus, they have two positive charges just
like a completely ionized helium ion .
a beta particle is a stream of a fast moving
electron, it has a charge of negative one and a mass of an electron.
According to the law of electrostatic force,
like charges attracts while unlike charges repels.
An alpha particle is positively charged,
therefore when subjective to an electro-magnetic field it will be deflected to
the negative pole.
A beta particle is negatively
charged when subjected to an electro-magnetic field it will be deflected to the
positive poles
Other properties of alpha particles
are they are helium nucleus, they are most ionizing radiations, they cause fluorescence
when they hit a photographic plates, they are most least penetrationg among, they
the slowest, they can be stopped by a thin sheet of paper or clothes and they
are the most dangerous radiations.
Beta ray have other properties apart from the above,
they are faster than alpha but slower
than gamma, they more penetrating than alpha particle but less than gamma rays,
they ionizes gases, they travel at speed
close to the speed of light, they
are penetration than alpha particles but less than gamma, they are cause fluorescence,
they deflected to the north pole in a
magnetic field
