Question

Which of the following describes a relationship between an atomic property and nuclear power generation?

A.
Atoms such as the uranium-235 isotope absorb energy when they are split into smaller atoms.

B.
Atoms such as the uranium-235 isotope can bond with other atoms to form larger molecules, releasing energy in the process.

C.
Atoms such as the uranium-235 isotope can bond with other atoms to form larger molecules, absorbing energy in the process.

D.
Atoms such as the uranium-235 isotope release energy when they are split into smaller atoms.

Answer 1

D

Nuclear power uses fission: heavy nuclei like uranium‑235 split into smaller nuclei and neutrons, and the process releases energy (mass defect → energy via E = mc²). Options B and C describe chemical bonding, and A states the opposite of what happens.
