Atomic Scale Chemistry

There is no real difference between chemistry and physics at atomic scale and if you read books on Molecular Physics or Quantum Chemistry or articles in the journals with those names, you will find similar subjects and phenomena described in both topics. Spectroscopy is usually considered to be a part of physics, while breaking and forming bonds between atoms is called chemistry. However, this does not provide a good border line either.

For example, such phenomena like Hardness and Elasticity, which at macro scale unquestionably belong to physics, at atomic scale are described by (de)formation and breaking bonds between atoms. Mass spectrometry, and particularly Secondary Ion Mass Spectroscopy (SIMS), are based on breaking chemical bonds and ionizing atoms and molecular fragments in order to analyze composition of a sample. SIMS is popular in Semiconductor Industry and is used to analyze composition of silicon wavers after deposition of thin layers or at other steps of device fabrication.

The pages you will find in this section are created by people who believe that they are chemists rather than physicists and believes are like love, you take them for granted if you want to live in piece.
