What are decay of radioactive atoms?

Radioactive atoms are like little time bombs inside some materials, and decay is when they pop and change into different kinds of atoms.

Imagine you have a big bag full of popcorn kernels. Each kernel is an atom, and sometimes the heat makes them pop. That’s kind of what happens with radioactive atoms, they get excited and pop to become something else.

What does decay do?

When a radioactive atom decays, it loses some particles or energy, turning into another type of atom. It's like when you take out the inside of a kernel and it becomes a fluffy piece of popcorn.

Sometimes this happens one by one, like a slow pop, and sometimes it happens all at once, like a big burst of popping sound from the whole bag!

These changes can make things glow, heat up, or even become new materials that we use in real life, like in hospitals to help people get better. Radioactive atoms are like little time bombs inside some materials, and decay is when they pop and change into different kinds of atoms.
