The elements that will not form bonds to other elements are the noble gases. These include:

* Helium (He)

* Neon (Ne)

* Argon (Ar)

* Krypton (Kr)

* Xenon (Xe)

* Radon (Rn)

Why don't they form bonds?

Noble gases have a full outer shell of electrons, meaning they have a stable electron configuration. This makes them very unreactive and unlikely to gain or lose electrons to form chemical bonds with other elements.

Exceptions:

While noble gases are generally unreactive, there are some exceptions:

* Xenon and Krypton: These heavier noble gases can form compounds with highly electronegative elements like fluorine and oxygen under specific conditions.

It's important to note that the term "noble gas" doesn't necessarily mean completely inert. It simply means they are less likely to form bonds compared to other elements.
