He2
Helium is a noble gas and will not join with itself or any other atom under normal conditions. The rest are common diatomic molecules.

AHe2 would be most unstable. It already has 8 electrons in its valence shell, having it form a bond would make it have a positive charge, and two adjacent positive charges is very very very unstable.
