Electron Arrangement H to Ca

May also benefit from the numeric electron structure notation (2,8,1 etc) for higher ability students. Otherwise very useful, saved a huge amount of time!

Certainly a good start to introducing atomic structure for the first 20 elements to students. Appreciate your effort in preparing them and sharing. Many thanks !

very useful thank you. jey Suku
