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

∙ 13y agothe 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.

Which type of radiation has no mass or charge?
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
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.''
What causes some of the alpha particles to bounce straight back from the gold foil?
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.
Which naturally occurring radioactive particle is the largest?
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 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.
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.
What is the mass and electrical charge of alpha particles?
2.00 lbs the charge is alpha-magnetic
Which type of radiation has no mass or charge?
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
Is it true that beta particles have a charge of2 plus?
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.
What is the charge of alpha particles?
+2 (2 x the absolute value of the charge of an electron).
What radioactive emanations have a charge 2 plus?
Alpha Particles
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.''
When an alpha particle joins with two beta particles what will be the total charge?
Neutral -zero charge
Does Beta particles have a charge of 2?
no alpha particle is the one that consist of particle with a 2+ charge
Does a beta particle have a zero 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.
How do the electric charges of alpha particles beta particles and gamma rays differ from each other?
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")]
How do the electric charges of alpha beta and gamma rays differ?
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.
