How to Write 铕 (yǒu) — Meaning “Europium”

Think of the right part 有 as 'have' in English, and imagine saying 'You have europium!' with the word 'you' sounding like yǒu. The left metal radical 钅 reminds you it's a metallic element. This mnemonic links the sound and meaning: 'you' (yǒu) for the metal.

Write the radical 钅 first as three strokes: left-falling, horizontal, vertical-falling. Then write 有 with its horizontal left-falling stroke first, then the left-falling and vertical strokes for 月. A common mistake is making the radical too wide or forgetting that 有 has a clear horizontal stroke at the top, not a dot.

The left radical is the same metal radical 钅 for all three, but the right side differs: 铕 has 有, 钙 has 丐, and 钚 has 不. In meaning, 铕 is Europium, 钙 is Calcium, and 钚 is Plutonium. Visually, remember that 有 has a top horizontal stroke and a moon-like bottom, while 丐 is simpler and 不 has a distinct shape.

铕 is used mainly in scientific and chemical contexts, such as in 铕元素 (Europium element) and 铕盐 (Europium salt). It appears in discussions of rare earth elements, phosphors in TV screens, and lasers. This character is not common in daily life but is important in chemistry and materials science.

Common words containing 铕 include: 铕元素 (yǒu yuán sù) — The element Europium; 氧化铕 (yǎng huà yǒu) — Europium oxide; 铕盐 (yǒu yán) — Europium salt.
