because the control of neucles on different electrons is different and we know that beta rays are infact electrons then we can say that the speed of beta rays emitted by the same element is different
U-235 emits beta particles as part of typical radioactive decay. When a beta particle is emitted, an electron is emitted and a neutron is converted into a proton.
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.
a beta particle
beta
It happens when a beta particle is emitted from the nucleus of the atom of element 92. Beta Particle is emitted when a neutron is converted to a proton.So atomic number that is , the no of protons increases by 1. Hence 92 becomes 93.

NovaNet: A beta particle is simply a high speed electron.
Positrons are emitted from proton-rich radioactive during positive beta-decay.

U-235 emits beta particles as part of typical radioactive decay. When a beta particle is emitted, an electron is emitted and a neutron is converted into a proton.
The most common type of beta-decay is beta-negative decay. A neutron decomposes to a proton, an electron, and an anti-neutrino. This involves one proton.
The alpha particle is emitted in alpha decay, and that means you won't see it appear in beta decay. In beta decay, you'll get either an electron or a positron emitted from the nucleus. A link to the related question here can be found below. "What is beta decay?" is already posted and answered.
False.
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.)
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle.

The three major forms of emitted ionizing radiation are Alpha, Beta and Gamma.
