Question

identify the process by which an unstable atomic number nucleus losses energy by emitting particles and also name thebparticles


If u answer this u will get 100 points

Answer 1

A beta particle, also called beta ray or beta radiation, (symbol β) is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively.


Beta particles with an energy of 0.5 MeV have a range of about one metre in air; the distance is dependent on the particle energy.

Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than alpha particles, but less ionising than gamma rays. The higher the ionising effect, the greater the damage to living tissue.

i hope this helps.
