The greatest problem in understanding the atomic structure is: the shell structure (ring diagram) and the orbital structure (box diagram), which remain disconnected. The concepts of subshells and orbitals (and suborbitals) is not effectively presented either in the ring diagram or in the box diagram. Quantum numbers are treated as though they are extraneous to the ring diagram or even the box diagram. What has been presented here is a Primer on atomic shell structure. ]]>

This presentation gives a simple introduction to green stains of copper on masonry. Unlike rust or efflorescent staining, copper staining on masonry has not been so traditionally frequently well experienced and therefore such instances of copper staining have not been so widely documented/shared as rust staining or efflorescence. Consequently, historically, we have not developed an established procedure to remove copper staining from masonry. With the current enthusiasm in copper architecture, copper staining of masonry deserves our attention; copper stains seen on the masonry in historical copper buildings also emphasize the need for a good restoration procedure from copper staining. We believe that this is an area where scientific problem solving by chemistry is required and the public need a reliable robust method to mitigate copper staining on masonry structures. Copper stain on masonry is a wonderful interplay of the unique features of copper chemistry and masonry chemistry. Calcium salts of organic acids can give a helping hand in copper stain removal. Poultice technique works the best. Suggestion is provided here for using calcium carbonate chalk as a model for masonry in lab scale investigations. ]]>

Renuka-Frayer Diagram is an improvised version of the Frayer diagram. It is fully adapted for application in New Generation Science Standards. This diagram is the state-of the art educational tool for individual as well as collaborative practices. It has been found very useful in the New Generation Science Standards for teaching as well as learning of disciplinary core ideas, cross cutting concepts; and science & engineering Practices.
