Atoms: the building blocks of life and the universe. We're all made of these microscopic bits of matter, but how many does it take to make a complete human being? And exactly what kinds of atoms do we have inside us?
The basic structure of an atom is made up of neutrons, protons and electrons, and its atomic number is calculated by adding up the number of protons and neutrons in the atom's nucleus. Learn about the basic structure and the atomic number of an atom in this article.
What exactly is an atom? What is it made of? What does it look like? The pursuit of the structure of the atom has married many areas of chemistry and physics in perhaps one of the greatest contributions of modern science!
