<u>Answer:</u> The correct answer
For 1: Gamma rays
For 2: Alpha particle
For 3: Beta particle
<u>Explanation:</u>
Gamma rays are the rays which are emitted when an unstable nuclei undergoes a spontaneous electromagnetic process known as gamma ray emission. This process is a decaying process. These rays have very high energy.
Alpha particle are the particles which are released when a radioactive isotope undergoes alpha decay process and changes the nucleus of the parent atom. This particle carrying a mass of +4 units and has a charge of +2.
Beta particle is a particle which is released when a radioactive isotope undergoes a beta decay process. The particle released carry -1 charge and another name for this particle is an electron.
Hence, the correct answer for Statement 1 is gamma ray, Statement 2 is alpha particle and Statement 3 is beta particle.
