Otto Hahn and Fritz Strassmann discovered fission by bombarding uranium with neutrons.Their discovery was made possible by finding one of the fission products,barium (Ba,atomic no.= 56) .What is a reasonable explanation for why they were unable to initially observe the other product,krypton (Kr,atomic no.= 36) ?
A) Krypton is a noble gas and it may have diffused out of the sample.
B) The isotope of krypton generated might have a short half-life and had undergone radioactive decay to some other element.
C) Krypton is a noble gas and therefore chemically unreactive,making it difficult to characterize by chemical means.
