Ok kiddo, so you know how the sun is really bright and it gives us light and warmth? Well, the sun is made up of these tiny little things called particles called "atoms". One of these atoms is called "sódium" or "Na" for short. Sódium is a metal and when it gets real hot, like in the sun, it melts and turns into a liquid called "sól" or "salt".
The sun doesn't just have sól in it though, there are lots of different atoms and particles that make up the sun. But we can observe sól on the surface of the sun when we look at it through telescopes.
Now, it's important to know that we shouldn't ever look directly at the sun because it's too bright and can hurt our eyes. But scientists who study the sun use special equipment to look at it safely and they can learn a lot about how the sun works by observing the different things they see, including sól.
So basically, sól is a type of metal that's found on the surface of the sun, and scientists study it to learn more about the sun and how it works.
