Which notation is used to represent gamma decay?

The correct answer is option 2.

Explanation:

There are 4 types of decay process, in which a radioisotope can become stable. They are:

1.) Alpha decay: In this process, alpha particles are emitted when a heavier nuclei decays into lighter nuclei. The alpha particle released has a charge of +2 units and has a mass of 4 units. The alpha particle released is also known as helium atom.

2.) Beta-decay: In this process, a neutron is converted into a proton and an electron with the release of a beta-particle. The beta particle released carries a charge of -1 units. and it does not have any mass.

3.) Gamma ray emission: In this process, an unstable nuclei releases excess energy by a spontaneous electromagnetic process and are emitted. These radiations does not carry any charge and are electrically neutral.

4.) Positron decay: In this process, a proton is converted to a neutron and an electron neutrino and positron particles are released. This particle carries a charge of +1 units and does not have any mass. This type of decay is also known as beta-plus decay.

From the above information, gamma decay is represented as  

Hence, the correct answer is Option 2.

γ

Explanation:

Hello,

In the process of gamma decay, it is stated that an unstable nuclei releases the spare energy it has by a spontaneous electromagnetic process so γ-radiations are emitted. Such radiations do not carry any charge and are electrically neutral, thus, the best way to represent this process is γ.

Best regards.
