Answer 2

➭ AnSwer :-

• When isotopes are unstable, meaning that they have an imbalance of neutrons and protons, they are radioactive.
• This atom is radioactive because it has too much energy, making it unstable.
• After a while, the extra energy will be released from the unstable atom.
• This process is called radioactive decay
