How the character is built
钅
The 钅 radical marks this as a metal, and that is not a coincidence of this one character — it holds right across the table. Read the radical first and the element's state at room temperature is already settled. It is 金 (jīn) squeezed into the space beside another component — radicals change shape by position, which is why 金 is hard to spot until you know to look for 钅.
Phonetic 哀 āi; Taiwan writes 鑀 ài — same syllable, different tone.
This character is used for the element and little else — you are unlikely to meet it outside a chemistry classroom.
