Why does helium exist only as single atoms?
Luna ChenHelium is a noble gas.
Helium atoms have a complete duplet and so it is highly stable.
Being stable, it doesn't need to form atomic bonds which elements with incomplete octets and duplets normally do to attain stability.Thus , it is found in elemental form

Kai BowmanDue to its complete outer electron shell, which makes it extremely stable and unlikely to form chemical bonds with other atoms, helium can only exist as a single atom.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
