how do atoms exist in millions of substances we see around us.
answer in more words
Answers
If we cannot see atoms, then how’d we know it actually exists? Science is known to offer pieces of evidence for each of its concepts. Hence, the evidence to prove atoms really exist is offered in a variety of forms. Scientists have actively split big atoms into smaller versions.
Based on a very popular series of experiments from the early 20th century, Ernest Rutherford led the team which fired particles towards atoms and observed them carefully. It revealed how orbits were arranged in the interior of a typical atom.
Furthermore, some substances are known to be radioactive; that is, they naturally fragment into simpler substances and emit tiny particles in the process. Once again, all of this makes sense when atoms exist and they are made from smaller particles.
In addition, there are numerous shreds of evidence to prove the presence of electron particles. Their contribution to power things like magnetism and electricity is quite renowned.

Answer:
Atoms are small. Really, really small. You’ll probably have heard that matter is made of bundles of these tiny things. You’ll likely also know that you can’t see them with the naked eye. We are told to take on trust the idea that atoms are there, interacting with each other and being building blocks for our world.
It might seem as if there’s a simple way to prove atoms exist: put them under the microscope. But this approach won’t work. In fact, even the most powerful light-focusing microscopes can’t visualise single atoms. What makes an object visible is the way it deflects visible light waves. Atoms are so much smaller than the wavelength of visible light that the two don’t really interact. To put it another way, atoms are invisible to light itself. However, atoms do have observable effects on some of the things we can see.
About 50 years later, in 1827, the Scottish botanist Robert Brown described something curiously similar. He had his microscope trained on some pollen grains. Brown noticed that some of the grains released tiny particles – which would then move away from the pollen grain in a random jittery dance.At first, Brown wondered if the particles were really some sort of unknown organism. He repeated the experiment with other substances like rock dust, which he knew wasn’t alive, and saw the same strange motion again.
