One day, when they were discussing about electronic configuration, Raman told Sonu that writing electronic configuration is very important as this helps in knowing why the substances present around us differ from each other like water flows but salt or ice does not? How can we improve their properties and make them more useful? He also told Sonu that while writing electronic configuration, always follow, Pauli's principle, Hund's rule and Aufbau principle.
