Fill in the blank : 9 2 2 3 5 U + 0 1 n → ? + 3 6 9 2 Kr + 3 0 1 n

Options

  1. A5 6 1 4 1 Ba
  2. B5 6 1 3 9 Ba
  3. C5 4 1 3 9 Ba
  4. D5 4 1 4 1 B

Correct answer

A. 5 6 1 4 1 Ba

Step-by-step solution

9 2 + 0 = Z + 3 6 + 0 ⇒ Z = 5 6 (Sum total atomic numbers) 2 3 5 + 1 = A + 9 2 + 3 (Sum total mass numbers) ∴ A = 1 4 1 Missing nuclide is 5 6 1 4 1 Ba
