what are atoms ?

A meteorite from spaos^'rock from Mars, a pea in the garden, the soil or our body cells, every substance in the universe is made up of minute particles called atoms.

Atoms combine in numerous ways to form different substances. For example, common salt has a combination of atoms which are different than that of water. Single atoms are far too small to be seen, even with the most powerful microscope. For example, about four billion atoms would fit side-by-side on the full stop at the end of this sentence.

Inside the atom are a variety of even tinier particles. These are called subatomic particles. They rarely exist on their own. Atoms are the smallest particles that may or may not exist by themselves. In other words, we can say that the atom of a substance can retain the properties of that substance. Every atom of iron will retain the properties of iron. If you break down an atom, the substance no longer exists.
