How many electrons fill helium outer shell

WebThis can be explained as an electron configuration and is designated as 1s1 (1 representing the electron shell, and s the subshell). The superscript 1 indicates one electron within the 1s orbital. Helium 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. WebIts electrons are filled in the following order: K shell – 2 electrons L shell – 6 electrons Therefore, the electron configuration of oxygen is 1s2 2s2 2p4, as shown in the illustration provided below.
