Zirconium

Traditional:

How the character is built

The 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 (jīn) squeezed into the space beside another component — radicals change shape by position, which is why is hard to spot until you know to look for .

Where you actually meet it

锆石 (gàoshí) zircon

The element itself

Zircon is the mineral that refuses to die: it survives weathering, transport, burial and even remelting, so grains of it get recycled through sediment for billions of years carrying their history intact. When it crystallises it accepts uranium into its structure and rejects lead almost completely, which means any lead found inside a zircon grain must have come from uranium decaying in place — the single most reliable clock in geology. Grains from the Jack Hills of Western Australia have been dated to about 4.4 billion years, older than any surviving rock, and they are the only direct sample we have of the earliest Earth.

Where it sits among the 118

Zirconium melts at 1855°C (2128 K) — lower than 14 of the 97 elements whose melting point has been measured, and higher than 82. The grey dots are the rest of the table.
In the Earth's crust there is about 170 grams in every tonne of rock. That makes it commoner than 75 of the 93 elements that occur naturally at all. The scale is logarithmic: each gridline is ten times the one below it.

First isolated in 1789.
