The alpha particle is the nucleus of a helium atom and hence has 2 protons and 2 neutrons. The neutron is neutral and the proton has a +1 elementary charge. The alpha particle therefore has an elementary charge of +2
the scientist named Dr. Ernest Rutherford discovered that alpha particles have positive electric charge in his experiment. in his experiment he took a small quantity of radioactive element in the cavity of lead block and photographic plate is setup close to it. he setup a strong magnetic field perpendicular to it and this placed in evacuated chamber. on examining the photographic plates he observed three types of radiations. according to fleming's left hand rule, the particles get deflected towards left has positive charge called alpha particles, the particles deflected towards right are negatively charged called beta rays and the particles that do not deflect are gamma rays and they have no charge.
Alpha particles have a positive electric charge.
An alpha particle is also a helium nucleus, and as such, has a charge of plus two.
+2 from the two protons. The two neutrons have no charge
+2, it is a fully ionized helium nucleus.
Positive, it contains two protons.

Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
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 composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
Alpha particles are the same size as a helium nucleus and are made up of 2 protons and two neutrons. They have no electrons so an alpha particle has a +2 charge
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.
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.
2.00 lbs the charge is alpha-magnetic
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
No. Beta- particles, electrons, have a charge of -1, and beta+ particles, positrons, have a charge of +1.The alpha particle has a charge of +2.
+2 (2 x the absolute value of the charge of an electron).
Alpha Particles

Neutral -zero charge
no alpha particle is the one that consist of particle with a 2+ charge
The particle that carries the positive charge (a proton) is much more massive than the particle that carries the negative charge (an electron) The charges are equal in magnitude though of opposite polarity.
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Alpha rays are positively charged, beta negatively charged and gamma rays is an electromagnetic wave(like light) which has no charge. They have obtained their charges on basis of where they originated from within the atom.
