How to Write 镥 (lǔ) — Meaning “Lutetium”

Think of "metal from Lǔ" — the left side is a metal radical, and the right side is the character 鲁 (lǔ). Picture a shiny metal bar (钅) next to a road sign marked "Lu" (鲁) to recall both the sound and the element category. This links the shape to the pronunciation and meaning together.

Write the left radical 钅 first as three strokes (撇, 横, 横, 竖提), then the right side 鲁 starting with the top 鱼 part. Common mistake is making the 钅 radical too wide — keep it narrow so the character balances. Also remember the lower part of 鲁 is 日 (sun), not 曰, and it has exactly 17 strokes total.

镥 (lǔ) uses the right component 鲁, while 镆 (mò) has 莫 on the right and represents the element moscovium, not lutetium. 镇 (zhèn) has 真 (zhēn) on the right and means "town" or "to suppress," not a chemical element. Visually, 镥 has more strokes on the right with the 鱼 and 日 parts, whereas 镆 has a larger 莫, and 镇 has a simpler 真.

镥 is a technical character used almost exclusively in chemistry and materials science to refer to the element lutetium, often in compound names like 氧化镥 (lutetium oxide). It is not found in daily conversations or HSK vocabulary. Learners may encounter it in scientific texts about rare-earth elements, but it is rarely needed for general language use.

Common words containing 镥 include: 镥元素 (lǔ yuán sù) — Lutetium element; 氧化镥 (yǎng huà lǔ) — Lutetium oxide; 金属镥 (jīn shǔ lǔ) — Lutetium metal.
