An electron configuration is a method of indicating the arrangement of electrons about a nucleus. A typical electron configuration consists of numbers, letters, and superscripts with the following format: A number indicates the energy level (The number is called the principal quantum number.).
This worksheet provides extra practice for writing electron configurations. The easiest and most reliable technique for writing electron configurations is to use the periodic table as your guide. Details of using the periodic table as a guide for determining electron configurations can be found on the CH301 website. 1.
