... its atoms. The noble gas elements, for example, all have similar chemical properties because the outermost energy levels of their atoms are completely filled. The chemical properties of ions also depend on the number of valence electrons. Any ion with a complete outermost energy level will have chem ...

... and nuclear fusion. As a basis for understanding this concept: a. Students know protons and neutrons in the nucleus are held together by nuclear forces that overcome the electromagnetic repulsion between the protons. b. Students know the energy release per gram of material is much larger in nuclear ...

EXPERIMENT 3 – Keto-Enol Equilibrium Using NMR
... However, NMR can be used to provide much more detail than just the molecular structure of small organic and organometallic complexes. It can also be used for connectivity, spatial and dynamic information about a wide variety of materials. There are many books that describe the basics of NMR spectros ...
