The helium has two electrons in its last electronic layer, being thus, this not need to make bonds with other helium elements, like do nitrogen or oxigen.
Because this last electonic layer has only one orbital that is a "s" orbital, that can keep only two electrons.
This element is a noble gas, like radonium, xenonium, argonium and kriptonium.
The formula of helium is represented by the atom of this element, that is He.
