Narrator: It is named after Tantalus, a king in Greek myth punished with unreachable food.

Narrator: "Tantalum capacitor" describes a small component that stores electric charge.

Narrator: It differs from niobium because tantalum is heavier and more expensive.

Narrator: "Conflict minerals" is a second pattern, because tantalum ore has been linked to mining disputes.
