Web14 jan. 2024 · The helium atom has only one electron on its shell, we have to put only one electron in its orbital and that will go in the 1s orbital as the S orbital can hold a maximum of two electrons, and is closer to the nucleus. Helium electron configuration He (2) = 1s2 (complete configuration). Step3: Determine Valence Shell WebThat is, it is possible to determine the properties of helium from the electron configuration. The last shell of helium has no unpaired electron, so the valency of helium is 0, and the last shell has a total of two electrons, so the valence electrons of helium are two.
