Question

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

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

Answer 1

The Correct Option is C

The question asks about the synthetically produced radioactive noble gas produced by the collision of Californium-249 (²⁴⁹Cf) with Calcium-48 (⁴⁸Ca).

• Oganesson (Og): The collision of Californium-249 with Calcium-48 results in the creation of Oganesson (Og), a highly radioactive noble gas with atomic number 118. It is a synthetic element.
• Radon (Rn): Radon is a naturally occurring noble gas and not formed in this reaction.
• Radium (Ra): Radium is a radioactive element, but not a noble gas.
• Xenon (Xe): Xenon is a naturally occurring noble gas, and it is not formed in this reaction either.

The correct synthetically produced noble gas is Oganesson (Og), so the correct answer is (C).

Answer 2

The noble gas produced by the collision of \( ^{249}_{98} \text{Cf} \) (Curium-249) with \( ^{48}_{20} \text{Ca} \) (Calcium-48) is Oganesson (Og).  
This was a synthetic element produced in a laboratory in 2002 by researchers at the Joint Institute for Nuclear Research (JINR) in Russia.  
It is a highly radioactive element and is part of the noble gas group. The element was named Oganesson in honor of Yuri Oganessian, a nuclear physicist.
