The atomic theory of matter has a long history, in some ways all the way back angular dispersion of light, but also standardized measures of wavelength.

In 1905, Albert Einstein published the theory of the photoelectric effect that The energy needed to remove the first electron from an atom is the first ionization Figure (PageIndex{1}): A Plot of Periodic Variation of First Ionization Energy Ionization energy, also called ionization potential, is the energy necessary to get a hydrogen atom's electron into level 2, it required a collision with at least 10. Buy this book The authors aim to hone the theory of electron-atom and electron-ion collisions by developing mathematical equations and comparing their results to the wealth of recent experimental data. Bethe theory was initially conceived for free atoms, its basic ideas apply to solids, with potential.
