How do you find the quantum number of an element?
Look at the Periodic Table of Elements and find the element that you want to know the quantum number for. Find the principal number, which denotes the element’s energy, by looking in which period the element is found. For example, sodium is in the third period of the table, so its principal quantum number is 3.

What is the electron configuration of Li?
1sยฒ2sยนLithium / Electron configuration
Lithium is the third element with a total of 3 electrons. In writing the electron configuration for lithium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining electron for Li goes in the 2s orbital. Therefore the Li electron configuration will be 1s22s1.
