What velocity does the electron that is emitted from a beta-decay have? And what velocity does the Alpha particle have when it's emitted?
Beta and alpha decay occur when an unstable atomic nucleus emits particles in order to become more stable. In beta decay, a neutron is converted into a proton and an electron is emitted from the nucleus. In alpha decay, a helium nucleus (two protons and two neutrons) is emitted from the nucleus.
Beta particles are high-energy electrons, while alpha particles are made up of two protons and two neutrons. Beta particles are much smaller and lighter than alpha particles and can travel much faster and farther than alpha particles.
Beta particles have velocities close to the speed of light, while alpha particles have velocities that are about one-tenth the speed of light. This is because alpha particles are much heavier and have a greater mass than beta particles.
The velocities of beta and alpha particles can be measured using various techniques, such as particle detectors or cloud chambers. These methods use the particles' interactions with matter to track their paths and calculate their velocities.
The velocities of beta and alpha particles can be affected by various factors, such as the energy of the emitted particle, the type of decay, and the properties of the nucleus itself. The presence of electromagnetic fields can also affect the velocities of these particles.
