Below are sample questions representative of the exercises included on this worksheet and related 11.120 Balanced Nuclear Equations skill assessments:

Problem 1Difficulty: Mastery
Which net equation balances neutron capture and beta-minus emission converting cobalt-59 to nickel-60?
A59_27Co + 1_0n -> 60_27Co + 0_-1e
B59_27Co + 1_1H -> 60_28Ni + 0_0gamma
C59_27Co -> 60_28Ni + 1_0n
D59_27Co + 1_0n -> 60_28Ni + 0_-1e
Solution & Explanation:The reactants total A = 60 and Z = 27. Nickel-60 plus a beta-minus particle totals A = 60 and Z = 28 + (-1) = 27.
Problem 2Difficulty: Mastery
Balance 100_42Mo + 1_0n -> 99_42Mo + x1_0n. What is x?
A1
B3
C2
D4
Solution & Explanation:The left side has mass number 101. Molybdenum-99 plus two neutrons gives A = 101, and all terms have atomic number 42 in total.
Problem 3Difficulty: Mastery
In 238_92U -> 206_82Pb + 84_2He + x0_-1e, what is x?
A4
B6
C5
D8
Solution & Explanation:Eight alpha particles reduce A by 32 and Z by 16, giving A = 206 and Z = 76. Six beta-minus particles raise Z to 82.
