Hint:Sublimation and deposition both are the processes which involve change in the physical state of the compound. In the sublimation process, compound in solid changes to gaseous and deposition is just the reverse of the sublimation process.
Complete step by step answer:
Both sublimation and deposition are the phase transfer process which refers to the change in physical state.
Sublimation is defined as the process where the substance present in solid state is directly changed into gases by skipping the liquid state.
The sublimation reaction is shown below.
The carbon dioxide present in solid form changes to gaseous form.
The deposition is defined as the process where the substance present in a gaseous state is directly changed into solid states.
The deposition reaction is shown below.
The carbon dioxide is gaseous form changes to carbon dioxide in solid form.
Both the sublimation reaction and deposition reaction are reverse of each other. The sublimation and deposition both show physical changes but in opposite directions.
The similarity between the sublimation and deposition is that both processes skip the middle state which is the liquid state.
As in sublimation solid directly changes to gases, the high amount of energy is required. Thus the sublimation is an endothermic process.
In a deposition reaction, heat is released. Therefore, the deposition is an exothermic process.
Thus the number of neutrons in sodium atom = .
Note:
The carbon dioxide present in the standard state exerts both the properties of sublimation and deposition. As deposition in a reverse of sublimation therefore, the deposition is also known as de-sublimation.
