∙ 6y agoAn alpha particle is actually a helium-4 nucleus (4He2+, or 24He++), and it's composed of two protons and two neutrons. This boson has a mass of about 6.644656 x 10-27 kg and that plus two charge (2e) that you see.
The alpha particle is a type of particulate radiationthat is emitted from the nucleus of some atoms as they undergo nuclear (radioactive) decay. The decay event is a form of quantum mechanical tunneling. Radium (226Ra) is a well known alpha emitter, and so is radon gas (222Ra), which is a radioactive daughter of radium. Alpha decay is the mode of decay of a goodly number of other different radionuclides, and not just these two. Further, if you guessed that an element that undergoes alpha decay is changed into another element, which is called nuclear transformation, you'd be correct.
Alpha particles are "heavy" as far as particulate radiation goes. Though they cannot travel far even in air and are easily stopped by a sheet of paper, they have tremendous power to ionize materials. Exposure to alpha radiation, which is usually due to ingestion or, more probably, inhalation of a radionuclide that is an alpha emitter, will result in large scale tissue damage in the area where it appears as decay radiation. It's bad news.
If you're wondering what eventually happens to an alpha particle, we can supply that information. In an alpha decay event, the alpha particle appears with a lot of kinetic energy. But it slows down quickly, and not long after it appears, it will collect a pair of electrons from its surroundings and become a helium-4 atom. Use the link to the Wikipedia post for more information. You'll find that link below.

∙ 11y agoAlpha particles (named after and denoted by the first letter in the Greek alphabet, α) consist of two protons and two neutrons bound together into a particle identical to a helium nucleus, which is classically produced in the process of alpha decay, but may be produced also in other ways and given the same name.

Particle with two protons and two neutrons ejected during decay?
An alpha particle. It is also a helium nucleus and has a charge of +2e. The ejection of an alpha particle occurs whenever the electromagnetic force overcomes the strong force in a nucleus and needs to rid itself of excess charge. The reason that a single proton is not simply ejected has to do with the stability of the alpha particle itself which is generated by the strong force. If there were more protons in an alpha particle, it would not hold together properly. It cannot have more neutrons because it simply wouldn't be ejected because of strong force.
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.
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.
The number of protons plus neutrons in an alpha particle?
2 protons and 2 neutrons. An alpha particle is the same as a helium nucleus.
What represents a alpha particle?
An alpha particle is sometimes symbolized by the Greek lower case letter alpha (α). Also, because an alpha particle, which is 2 protons and 2 neutrons, is the nucleus of a helium-4 atom, you may see He2+ or 42He2+ used to write (symbolize) an alpha particle. This is particularly true in nuclear equations that are balanced in a manner similar to a chemical equation. Links can be found below.
What is a stream of particles containing two neutrons and two protons?
The particle described is an alpha particle, and we might call a stream of them alpha radiation or an alpha ray.
How manyneutrons are in an alpha particle?
There are 2 neutron in an alpha particle.

Which of these masses is the largest alpha particle antineutrino gamma radiation beta particle?
Alpha Particle
The nucleus of a helium atom is called?
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
Is alpha particle non fundamental?
Yes, the alpha particle is nonfundamental.
Is alpha wave or particle?
Alpha is a particle not a wave. Alpha particle are positively charged helium nuclei and have a +2 charge and 4u mass.
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
What are the characteristics of an alpha particle?
An alpha particle has the charge 2+ and the mass 4.
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.
Is an alpha particle is identical to the nucleus of a?
An alpha particle is identical to the nucleus of Helium atom
