Extinct isotopes of superheavy elements

Imagine you have a lot of puzzle pieces that you need to put together to make a picture. The puzzle pieces represent atoms, which are the building blocks of everything around us.

Now, some of these atoms are called isotopes, which means they have the same number of protons but a different number of neutrons in their nucleus, the center of the atom. Think of the nucleus like the head of the puzzle piece.

Superheavy elements are atoms that have a lot of protons in their nucleus, which makes them very heavy. Scientists make these superheavy elements by smashing smaller atoms together.

However, some of these superheavy elements are unstable, which means they won't last very long before they break apart into other atoms. This is kind of like if you tried to build a really tall tower out of blocks, but it kept falling over because it was too wobbly.

When these superheavy elements break apart, they can form other isotopes, meaning they have different numbers of neutrons than the original atom. And sometimes, the new isotopes that are formed are very rare and don't last very long before breaking apart into even smaller atoms. These rare and short-lived isotopes are called extinct isotopes.

Scientists are interested in studying these extinct isotopes because they can tell us more about how these superheavy elements break apart and how they behave in different environments. It's like if you were trying to figure out the best way to build a really tall tower out of blocks - if you knew which blocks kept falling apart, you could figure out how to make your tower stronger and last longer.
