How small is an atom? (Persian subtitle)

One of the most important questions that every curious person has probably asked themselves once (after the question of where I came from, what was the purpose of my coming!) is how small atoms really are and whether they can have a material nature. became? Apart from the second part of this question, which is probably beyond the scope of this video and article, the first part can be simulated, so that you can understand the wonders of the atom with its help.

But before anything else, permission Let's talk a little about the familiar atomic model that you probably saw in your elementary school science book. The atomic model in which the nucleus is in the middle of the atom in a rigid form and electrons are circulating around it. In general, you should know that the atom is not like this and the model you have seen is not drawn with the correct scales, it is very, very simple and it is very different from what we expect from the reality of atoms. But what do we know about the atom itself and its size?

Imagine that we have a grapefruit that consists only of hydrogen atoms. Now if I blow up each atom of this fruit to the size of a blueberry, our grapefruit is the size of the entire globe, which is literally amazing. But there is also a visualization about the nucleus of atoms and how small this part of the atom is. Let's go back to the story of grapefruit. If we look for any of the blueberries of this fruit, we will see that it is not so easy to find the core! Imagine that the blueberry in our story is the size of a football stadium, in this case, the presence of a marble inside the stadium can be considered a symbol of the nucleus of the atom!

But the story does not end there and in the upcoming video About the world of atoms, we show you this strange world with other surprising facts.
