Solution

Solution Steps

Step 1: Understanding Radioactive Isotopes

Radioactive isotopes, also known as radioisotopes, are atoms with an unstable nucleus. This instability is due to an imbalance in the number of protons and neutrons.

Step 2: Identifying the Correct Statement

Radioactive isotopes undergo radioactive decay to achieve a more stable state. During this process, they release energy in the form of radiation.

Step 3: Evaluating the Options

Option 1: They are unstable, but can become stable by bonding with other isotopes. (Incorrect, as bonding does not stabilize the nucleus.)
Option 2: They are stable and will decompose, releasing energy. (Incorrect, they are unstable.)
Option 3: They are stable and can participate in chemical bonding. (Incorrect, they are unstable.)
Option 4: They are unstable and will decompose, releasing energy. (Correct, this describes the process of radioactive decay.)
