Question

The synthetically produced radioactive noble gas by the collision of \(^{249}_{98}\text{Cf}\) with \(^{48}_{20}\text{Ca}\) is:

• A. Radon
• B. Radium
• C. Oganesson
• D. Xenon

Hint:

Oganesson is synthesized by colliding Cf-249 and Ca-48, producing Og-294 and neutrons.

Answer 1

The Correct Option is C

The given question asks which synthetically produced radioactive noble gas is formed by the collision of \(^{249}_{98}\text{Cf}\) with \(^{48}_{20}\text{Ca}\). Let's analyze the process and find the correct answer. 

Understanding the Process:

The collision of californium (\(^{249}_{98}\text{Cf}\)) with calcium (\(^{48}_{20}\text{Ca}\)) nuclei is a nuclear reaction used to synthesize superheavy elements. In these reactions, two nuclei combine to form a heavier nucleus.

Synthesis of Oganesson:

Oganesson (Og) is one of the superheavy elements that belong to the noble gas group. It was first synthesized in 2002, with the atomic number 118 and symbol Og.

The reaction can be represented as follows:

\(^{249}_{98}\text{Cf} + ^{48}_{20}\text{Ca} \rightarrow ^{294}_{118}\text{Og} + 3 \ ^{1}_{0}\text{n}\)

Thus, during the reaction, three neutrons are released, and Oganesson is produced.

Justifying the Correct Option:

• Radon: Radon is a naturally occurring radioactive noble gas, not produced synthetically through such reactions.
• Radium: Radium is an alkaline earth metal, not a noble gas.
• Oganesson: As analyzed, it is the result of synthesizing \(^{294}_{118}\text{Og}\) from this reaction, and it is a noble gas.
• Xenon: Xenon is another noble gas, but it is not produced in this reaction.

Therefore, the synthetically produced radioactive noble gas is Oganesson.

Conclusion:

By understanding the nuclear reaction between \(^{249}_{98}\text{Cf}\) and \(^{48}_{20}\text{Ca}\), we conclude that the correct answer is Oganesson. This matches with option 3.
