Atomic physics

Atomic physics is like playing with really small building blocks. You know how you can build a tower out of blocks? Well, atoms are like the building blocks of everything in the world.

Just like how different colored blocks can make different towers, atoms can join with other atoms to make different substances. And just like how you can take apart a tower by removing blocks, scientists can study atoms by taking them apart and looking at what they're made of.

Atoms are made up of even smaller pieces called protons, neutrons, and electrons. Protons are like the red blocks, neutrons are like the blue blocks, and electrons are like the yellow blocks.

Scientists can use special machines to "look" at these tiny pieces, and they can even make the atoms smash together to make even smaller particles. This helps us understand how everything in the world works!
