So we know that all matter is made up of atoms, but what is an atom made out of? Chemists describe the structure of atoms using models. This section will cover the Bohr model, photoelectric effect, absorption and emission spectra, quantum numbers, and electron configurations.
How did scientists figure out the structure of the atom, and how did they discover subatomic particles? The answer is X-ray vision (just kidding!). In this section, we will discuss some of the awesome experiments in science history that led to our modern understanding of atomic structure.
