The extra energy, or radiation, emitted by radioactive elements comes in three different types: alpha, beta, and gamma. Alpharadiation is a stream of alpha particles, which are positively charged. They're fairly large, whichmeans they have a difficult time getting through materials like clothes and paper.

here's ur answer ⤵⤵⤵⤵⤵
Radioactive elements have radioactivity. Radioactivity is a spontaneous process which does not depend upon external forces like temperature, pressure etc. radioactive element in a state of disintegration which depends upon law of chance. it means it is impossible to predict which particular atom of radioactive element will disintegrate in a given time interval.
During disintegration of an atom either an, alpha particle or a beta particle is emitted. Both these particles are never emitted simultaneously. Also at a time, an atom will not emit more than one alpha particle or more than one beta particle.
More on radioactivity :-
Radioactivity is the spontaneous emission of energy from unstable atoms. As you know atoms are found in all matter. There are stable atoms, which remain the same always, and unstable atoms, which break down or 'decay' into new atoms. These unstable atoms are said to be 'radioactive', because they emit radioactivity from the nucleus as they decay. The phenomenon of radioactivity is observed in heavy elements such as uranium. A.H Bacqueral, a French scientist discovered radioactivity in 1896 by chance while performing an experiment. So radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability.
