How to calculate electron configuration?
If you want to do manually then follow the steps below to write shorthand electron configurations: First, find the required element on the periodic table. Now, find the atomic number of the first noble gas in the periodic table. Write the noble gas symbol in parentheses to start its electronic configuration. Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons.
