An analysis of the development of the atomic theory

Isotopes of hydrogen The most abundant isotopehydrogen-1, protium, or light hydrogen, contains no neutrons and is simply a proton and an electron. Protium is stable and makes up Deuterium is stable and makes up 0. Tritium contains two neutrons and one proton and is not stable, decaying with a half-life of Because of the short half life, tritium does not exist in nature except in trace amounts.

The formulas below are valid for all three isotopes of hydrogen, but slightly different values of the Rydberg constant correction formula given below must be used for each hydrogen isotope. Hydron chemistry Hydrogen is not found without its electron in ordinary chemistry room temperatures and pressuresas ionized hydrogen is highly chemically reactive.

Ionized hydrogen without its electron, or free protons, are common in the interstellar mediumand solar wind. Theoretical analysis[ edit ] The hydrogen atom has special significance in quantum mechanics and quantum field theory as a simple two-body problem physical system which has yielded many simple analytical solutions in closed-form.

Failed classical description[ edit ] Experiments by Ernest Rutherford in showed the structure of the atom to be a dense, positive nucleus with a light, negative charge orbiting around it.

This immediately caused problems on how such a system could be stable. Classical electromagnetism had shown that any accelerating charge radiates energy described through the Larmor formula.

Development of Atomic Structure J. J. Thomson () identified the negatively charged electron in the cathode ray tube in He deduced that the electron was a component of all matter and calculated the charge to mass ratio for the electron.

In the development of the atomic theory there were many scientists that contributed to it by experiments, research, and hard work. Because of what all these scientists researched and learned we have all this information on the atomic theory today.
