WebHelium only has 2 electrons and therefore it has a configuration of 1s2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas. 2. what is the electron configuration of Helium? Answer: WebHelium has two electrons, both in the first energy shell so is designated as 1s2. All of the space in the first energy shell is now filled. Lithium has three electrons; two of them are in the first shell, and the third electron is in the second electron shell: 1s22s1. players championship dates 2023 https://jdgolf.net
