An alpha particle is two protons and two neutrons, this is the same as a helium nucleus.
There are 2 neutron in an alpha particle.
Rutherford proved it it from his alpha-particle scattering experiment.
No, alpha decay does not directly produce helium atoms. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This alpha particle is the same as a helium-4 nucleus, but it is not considered a helium atom until it captures electrons and becomes electrically neutral.
Alpha Particle
Yes, the alpha particle is nonfundamental.
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
An ionizing particle, such as an alpha or beta particle, leaves a long thin trail in a cloud chamber due to its interactions with the gas atoms in the chamber, causing condensation along its path. This trail can help scientists track and study the particle's properties and behavior.
An alpha particle is most likely to transfer its energy through ionization and excitation of atoms in the medium it passes through. This process involves the removal of electrons from atoms and the promotion of electrons to higher energy levels, resulting in the production of free radicals and secondary particles.
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
This depends on the velocity, or temperature, of the alpha particle. The faster the particle goes, the higher its temperature, and the more energetic it is. When we are dealing with atoms and subatomic particles, temperature and velocity are pretty much measurements of the same thing. Most alpha particles emitted from large radioactive atoms have energies in the range of 3 to 7 MeV (million electron volts). Alpha particles from the decay of the heavier, man-made atoms can be more energetic yet. 5 MeV would mean that the particle is going about 15,000 km/s, or about 5% of the speed of light. At that speed, the alpha particle can be absorbed by a piece of thin paper. They are not horribly dangerous, if the particles are outside you. But if they are emitted from something inside you, they can be very destructive because they can alter living cells. It should be noted that an alpha particle is essentially the same thing as a Helium-4 nucleus. The difference is that the alpha particle came from nuclear decay, and is moving.
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
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.
