B- particles are electrons. They are not Helium nuclei.
Alpha and beta particles are the same in that changes in unstable atomic nuclei can release alpha particles or can beta particles (depending on the isotope involved), and both are forms of particulate radiation.
No. The difference between them is that helium atoms have electrons, and alpha particles don't.
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
Alpha radiation: this consists of fast moving helium nuclei - i.e. two neutrons and two protons. Beta radiation: this is composed of single electrons. Gamma radiation: very high frequency, high energy electromagnetic radiation.
Alpha rays are called helium nuclei because they consist of two protons and two neutrons, which is the same composition as a helium nucleus. When an atom undergoes alpha decay, it emits an alpha particle, which is essentially a helium nucleus that is ejected from the atom.
The particle that is the same as a helium nucleus is an alpha particle. It consists of two protons and two neutrons bound together. Beta particles are high-energy electrons or positrons, while gamma rays are electromagnetic radiation.
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
Neither, the strength of the gravitational force between the subatomic particles inside nuclei is negligible compared to the strength of both the weak nuclear force or the strong nuclear force between the same subatomic particles inside those nuclei.
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
The notations used to represent an alpha particle are either "a," "α^2+," or "He^2+." Alpha particles only have two protons and two neurons, making them essentially the same as helium nuclei, hence "He^2+."
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
