No, an alpha particle is not identical to an electron. An alpha particle is a helium-4 nucleus, and it's composed of a pair of protons and a pair of neutrons fused together. It several thousand times the mass of an electron, and has twice its charge with an opposite sign (+2). An electron is that little negatively charged (-1) elementary particle that we find whizzing around atoms. You'll find a pair of related questions linked below.
What else can I help you with?
What particle alpha or beta is more massive?
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
Is alpha particles heavier than beta particles?
Yes. A beta particle is just an electron, while an alpha particle is effectively a helium nucleus - two protons plus two neutrons. Protons (and neutrons) are each about 2000 times heavier than an electron. Therefore, an alpha particle is about 8000 times heavier than a beta particle.
Are alpha particles or beta particles more highly charged?
An alpha particle has a charge of +2 (elementary charges). A beta particle has a charge of -1 (electron) or +1 (positron).An alpha particle has a charge of +2 (elementary charges). A beta particle has a charge of -1 (electron) or +1 (positron).An alpha particle has a charge of +2 (elementary charges). A beta particle has a charge of -1 (electron) or +1 (positron).An alpha particle has a charge of +2 (elementary charges). A beta particle has a charge of -1 (electron) or +1 (positron).
A beta particle differs from an alpha particle in that it?
A beta particle is an electron or a positron, with a charge of -1 or +1, and a mass of about 1/1836 of a proton. An alpha particle, on the other hand is a helium nucleus, with a charge of +2, and a mass of two protons and two neutrons. The beta particle has more penetration ability than the alpha particle, but the alpha particle is more biologically dangerous when in close proximity to sensitive tissue, such as when inhaled into the lungs.
How much alpha particle is heavier than neutron?
An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at 1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
Which has the largest mass alpha particle gamma ray positron or beta particle?
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
What particle alpha or beta is more massive?
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
A beta particle is actually?
A beta particle is an electron or positron emitted during radioactive decay. It has a charge of -1 for electrons and +1 for positrons, and is lighter than an alpha particle. Beta decay occurs when a neutron in the nucleus decays into a proton, electron, and antineutrino.
Is alpha particles heavier than beta particles?
Yes. A beta particle is just an electron, while an alpha particle is effectively a helium nucleus - two protons plus two neutrons. Protons (and neutrons) are each about 2000 times heavier than an electron. Therefore, an alpha particle is about 8000 times heavier than a beta particle.

Who is the smallest electron neutron proton or alpha particle?
Protons and neutrons are the same size relatively, and are bigger than alpha particles and electrons; but, electrons are smaller than alpha particles.

Why alpha particle has lowest specific charge than electron and protonGive reason?
The question is incorrect. (Either that, or I don't know what "specific charge" means.) The alpha particle has a charge of +2, while the proton is +1 and the electron is -1.If you are talking about charge to mass ratio, however, it is true that the alpha particle has a mass of about 4 amu, while the proton is 1 amu, and the electron is 1/1836 amu. This makes the charge to mass ratio of the alpha particle to only be about 0.25, while the proton is 1.0 and the electron is -1836.
A beta particle differs from an alpha particle in that it?

Which particle is the lightest particale in the following 1. electon 2. neutron 3. proton 4. a-particles?
The electron is the lightest particle in the list. A proton is 1836 times more massive than an electron. Neutrons are just slightly more massive than a proton, and an alpha particle consists of two protons and two neutrons.
