Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food

India to victory at sea during a war! Batteries helped submarines to stay underwater and strike the enemy! Submarine batteries are nothing but electrochemical cells! That’s why electrochemistry is so important and everyone should try it!! 6 Inside a space craft: How do people get oxygen inside a space craft? 7 Electrolysis is an important aspect of electrochemistry! 8 So there are plenty of reasons why we should learn electrochemistry! From submarines to space crafts

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
