How are alpha and beta particles the same?
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.
Why alpha rays called helium nuclei?
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.
Would there be a stronger gravitational force acting among the particles of a helium nucleus or the particles of a uranium nucleus Explain?
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.
Is beta the same kind of radiation as alpha but does not have particles?
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.
What is made of protons and neutrons but not electrons?
Atomic nuclei (and alpha particales, but these are exactly the same as Helium nuclei)
Are beta emission and beta decay the same?
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.)
Do alpha particles and helium atoms have same electrons?
No. The difference between them is that helium atoms have electrons, and alpha particles don't.
Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
Which notation is used to represent a beta particle?
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+."
Are alpha particles big or small?
Absolutely small ... they're the nucleus of a helium atom (2protons & 2 neutrons) - But they are gigantic as compared to a beta particle ... which is just a free electron. - Note that gamma rays don't have any (rest) mass ... they're just radiation.
Does alpha particles have less mass the beta particles?
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.
Which is not one of the waves of the electromagnetic spectrum - UV rays or Alpha rays or Visible light or Infrared rays?
Alpha rays are not part of the electromagnetic spectrum. Alpha particles are the same as helium nuclei, and are given off in nuclear decay.
