unreactive
Won't form bonds
Unreactive describes something that doesn't readily respond or engage in reactions.
In chemistry, an unreactive substance resists combining with other elements: Noble gases are largely unreactive.
The term extends to people who show little emotional response: He remained unreactive to the criticism, his expression unchanged.
