The first two letters in the Greek alphabet. In statistics the alpha level is the probability that you will wrongly reject the null hypothesis. This is also referred to as a false positive. The beta level is the probability that you will wrongly retain the null hypothesis (false negative). Software that is under development, unstable or still being tested is referred to as being 'in alpha' or 'in beta'. Alpha usually denotes a 'developer release' only. Software moves out of alpha into beta stage when it is ready for wider 'bug' (error) testing by the average user. Software deemed reliable and bug-free then moves out of beta into general release.

If the mixture of electrically neutral how many more beta particles than alpha particles are in the balloon?
alpha particles would have twice as many beta particles
How does the penetrating ability of gamma rays compare with that of alpha particles and beta particles?
Gamma rays are more penetrating than alpha and beta particles.
Alpha or beta types of radiation is composed of particles with a charge and mass identical to that of an electron?
beta
Why are alpha and beta rays deflected in opposite directions in a magnetic field?
An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.
What type of radiation alpha beta or gamma is emitted by thorium-230?
alpha particles.
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.

Alpha particles and beta particles differ in?
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Both Beta and alpha particles can be blocked by a block of lead. Alpha particles can even be blocked by a sheet of paper, and beta particles can be blocked by a thin aluminium plate.
If the mixture of electrically neutral how many more beta particles than alpha particles are in the balloon?
alpha particles would have twice as many beta particles
How would you list alpha particles beta particles and gamma rays in order of increasing energy?
Alpha, beta, gamma.
How does the penetrating ability of gamma rays compare with that of alpha particles and beta particles?
Gamma rays are more penetrating than alpha and beta particles.
What is a beta emitter?
In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
The transformation of 92U238 into 82Pb206 the number of alph and beta particles is what?
alpha particles=8 and beta particles=6
How does it go from beta to alpha particles?
It's not possible to change beta particles to alpha particles or vice versa; they're two very different things produced by different processes. Beta particles can be either electrons or they can be positrons, which are anti-electrons. Alpha particles are helium-4 nuclei, which are composed of a pair of protons and a pair of neutrons. Beta particles are produced in beta decay (one in each type), and alpha particles are produced in alpha decay. Both of these types of nuclear decay release particulate radiation. Links can be found below to check things out.
Why does the path of the beta particles bend more than the path of the alpha particles?
Beta particles (electrons) are less massive than alpha particles (Helium-4 nuclei), by a factor of approximately 8000.
Why are reactions that emit alpha particles generally considered more safe than those that emit beta particles?
Alpha particles are actually electron-less helium nuclei versus beta particles which are actually electrons, which are much smaller than alpha particles. Therefore, alpha particles' penetrating strength is much smaller than beta particles (a sheet of paper versus a wooden board). Therefore, beta particles will penetrate more into a human body and will do more damage than alpha particles which are usually stopped at the skin.
