- Gallium + TelluriumGallium telluride 2Ga + 3Te → Ga₂Te₃ · When heated · Try it
- Gallium + IodineGallium iodide 2Ga + 3I₂ → 2GaI₃ · When heated · Try it
- Gallium + Hydrochloric AcidGallium chloride + hydrogen gas 2Ga + 6HCl → 2GaCl₃ + 3H₂ · At room temperature · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 13 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
