  1. A nucleus of uranium undergoes fission.
    ¹₀n + ²³⁵₉₂U → ¹⁴¹₅₆Ba + ˣ₃₆Kr + 3¹₀n
    What is correct about the number of nucleons x in the Kr nucleus and the ratio (binding energy per nucleon of Kr) / (binding energy per nucleon of Ba)?
Table with four rows (A-D) and two columns. The first column is 'Number of nucleons x in Kr nucleus' and the second column is 'binding energy per nucleon of Kr / binding energy per nucleon of Ba'.
