Just how big is the atom?
Watch this video as an introduction to this topic. How much do you actually know about the atom? What particles could you find inside? And where?
The atom
The atom
An atom has a central nucleus. This is surrounded by electrons arranged in shells. The nucleus is tiny compared to the atom as a whole. The nuclei of all atoms contain subatomic particles called protons. The nuclei of most atoms also contain neutrons.
