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.
Stable isotopes are chemical isotopes that are not radioactive, meaning that they do not spontaneously undergo radioactive decay.
All radioactive isotopes are unstable and they decay to a stable isotope emitting particles.
when an isotope is it does not undergo radioactive decay
They don't so much disappear as become converted to a different isotope - as they throw off particles. If you took the remaining material and added the mass of the particles released as radiation, you should still get the same mass as the original material before the radioactive decay.
A radioisotope is a radioactive isotope. When radioisotopes decay, they spontaneously emit particles and radiation. Radioisotopes are commonly used in scientific research and medicine.
alpha: mass 4, charge +2beta: mass ~1/1800, charge -1gamma: mass 0, charge 0

Yes, plutonium-239 emits alpha particles by decay.
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
The life of an isotope depends on whether it is stable or not. Stable isotopes do not decay and therefore, do not have an lifetime since they do not go away. Unstable isotopes decay at predictable rates. However, each unstable isotope decays at a its own rate. Therefore, the life of an unstable isotope depends on the isotope in question. Some isotopes have extremely short lifetimes (milliseconds) and other have extremely long lifetimes (billions of years).
Either an Alpha particle or Beta particle depending on what isotope it comes from
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
