Scientist create element 117 from calcium & Berkelium.
A
Correct answer
Explanation
Element 117 (Tennessine) was first synthesized in 2010 by a Russian-American team through nuclear fusion, bombarding berkelium-249 with calcium-48 ions. This process of creating superheavy elements by fusing lighter nuclei is well-documented. The claim that scientists created it from calcium and berkelium is factually correct.
