Helium 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. This means it will not react with other atoms.
