Iridium (element)
銥 represents the chemical element iridium, a hard, brittle, silvery-white metal. Its meaning is entirely tied to this specific element.
銥 is a modern character created to represent the element iridium. It combines the metal radical 金 with the phonetic component 衣 (イ), following the typical pattern for chemical element kanji.
The left side 金 (metal) tells you it's a metallic element, and the right side 衣 (clothing) hints at the sound. Picture a shiny iridium-coated piece of clothing to remember it's the metal iridium.
For イ, think of an iridium earring (イヤリング) — the first syllable イ matches the reading, and the metal 金 on the left reinforces the connection.
