It was discovered in 1802 and named after King Tantalus from Greek mythology — according to legend, he \"refused to drink water,\" just as tantalum refuses to absorb acid. In fact, tantalum is exceptionally resistant to corrosion, even in the most aggressive acids.\u003c\/p\u003e\n\n\u003cp style=\"font-weight: 400;\"\u003e \u003c\/p\u003e\n\n\u003cp style=\"font-weight: 400;\"\u003eWhat makes tantalum exceptional?\u003c\/p\u003e\n\n\u003cp style=\"font-weight: 400;\"\u003e✅ **Rarity** – tantalum is extremely rare: it occurs in the Earth's crust at an average of less than 1 gram per ton of rock.
