Answer from: lilisncz

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.

$_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}+_2^4\alpha$

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.

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$

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

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$

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.

$_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e$

From the above information, gamma decay is represented as $_0^0\gamma$

Hence, the correct answer is Option 2.

Answer from: TheOverlordOfWhales

^0_0 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 ^0_0 γ.

Best regards.
