How to Write 钌 (liǎo) — Meaning “Ruthenium”

Think of the phrase 'a little piece of metal' — the right part 了 sounds like 'liǎo' which is similar to 'little', and the left part 钅 means metal. So you can remember ruthenium as 'a little metal'.

Write the left radical 钅 first with 5 strokes: three horizontal strokes and two vertical ones, then add the right part 了 with 2 strokes (horizontal hook and vertical hook). A common mistake is making the right part too big — keep it compact and even with the left side.

钅 is just the metal radical and is not a standalone character, while 钌 is a full character meaning ruthenium. The character 钆 (gá) looks similar but has a hook on the right (乚) instead of 了, and it means gadolinium, another element.

钌 is used mainly in scientific and chemical contexts to refer to the element ruthenium, such as in 钌元素 (ruthenium element) or 钌金属 (ruthenium metal). It is not common in daily conversation and is typically found in textbooks or technical articles about chemistry and materials.

Common words containing 钌 include: 钌元素 (liǎo yuán sù) — Ruthenium element; 钌金属 (liǎo jīn shǔ) — Ruthenium metal; 含有钌 (hán yǒu liǎo) — contains ruthenium.
