Explanation:

• Option A: A radioactive atom is defined as one that undergoes nuclear decay and emits energy (in the form of particles or electromagnetic radiation) during this process.
• Option B: A cation is a positively charged ion formed by losing electrons, not related to nuclear decay.
• Option C: An anion is a negatively charged ion formed by gaining electrons, also not related to nuclear decay.
• Option D: "Energetic" is a general term and does not specifically refer to atoms emitting energy via nuclear decay.

Answer:

A) radioactive.
