Question

Match the following items.

1. high-intensity bundle of energy being emitted from some decaying nuclei
2. particle radiating from the nucleus of some atoms
3. negative particle identical to an electron but radiating from a decaying nucleus

-beta particle
-gamma rey
-alpha particle

Answer 1

Number two is the Alpha particle

Number one is the Gamma-ray

Number three is the Beta particle

Hope this helped. 

Answer 2

Answer: The correct answer

For 1: Gamma rays

For 2: Alpha particle

For 3: Beta particle

Explanation:

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.
