  1. Question 1

    Q1. If a U-238 nucleus splits into two identical parts, the two nuclei so produced will be:

    • A) Radioactive
    • B) Stable
    • C) Isotopes
    • D) Isobars

    Answer: Radioactive

    Explanation: When U-238 fissions into two equal parts (mass ~119 each), the resulting nuclei have a proton-to-neutron ratio far from stability and are thus radioactive.
