what is atom ????????
Answers
Explanation:
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
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.
