so it is easier to understand. Look in a microscope afterwards to see the real thing
Becuase atoms are so small that scientist have create models to describe them.

how the atoms are connected #8th grade science :)
Models are used to show the arrangement of the atoms in a molecule.
It was found that atoms are made up of even smaller particles (through experiments), and the models changed because how we thought atoms were composed turned out to be wrong, and corrections were made accordingly.
Because everything is comprised of them!
Atoms are too small to see.
