A very clear PowerPoint presentation showing the 'arrows in boxes' electronic sub shell filling order from hydrogen to krypton. My students find this very helpful and it is useful when printed as a handout. It also shows clearly the incomplete 4s subshell in chromium and copper.
Electronic configurations presentation
Brilliant. Very clear, illustrates all the rules for electron configuration all in one.
Like this! Very clear and effective. Thanks :)
very simple to understand especially filling up the shells. Thanks for making it easy !
