Hydrogen: the simplest atom
An atom of hydrogen consists of one proton (constituting the nucleus) and one electron. This simplicity of atomic structure means that H is of great importance in theoretical chemistry, and has been central in the development of atomic and bonding theories. The nuclear properties of the hydrogen atom are essential to the technique of 1H NMR spectroscopy .
In this chapter, we extend our discussions of hydrogen, looking at the properties of the H+ and H- ions, properties and reactivity of H2, and aspects of binary hydrides.
