Barium Research Paper Mr.Martin Block 1 May 18th‚ 2012 Abstract Barium was discovered in 1779 by Carl Scheele‚ but was isolated for the first time in 1808 by an English chemist by the name of Sir Humphry Davy. Barium is commonly found as BaSO4. Things that glow in the dark are made from Barium. Barium has many uses and plays a big role in our environment today. Barium can be found almost anywhere in the environment because it is produced there naturally and sometimes affects the environment

experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few. Molecular geometry is associated with the specific orientation of bonding atoms. A careful analysis of electron distributions in orbitals will usually
