How to Write 钡 (bèi) — Meaning “Barium”

Imagine a metal shell (贝) that is extremely heavy - that's barium, a dense metallic element. The radical 钅 tells you it's a metal, and 贝 sounds like "bay" - think of a bay filled with heavy metal barium. This visual link between metal and shell helps recall both the sound and meaning.

Start by writing the radical 钅: the first stroke is a left-falling diagonal (撇), then two horizontal lines, and finally a vertical hook (竖提). After that, write 贝: the left vertical stroke follows, then the horizontal fold (横折), and finally two small strokes for the inner legs and a closing horizontal line. A common mistake is making the metal radical too wide or forgetting the vertical hook - keep the left part narrow and compact.

While all three use the metal radical 钅, 钡 has the phonetic component 贝 (bèi, shell), whereas 针 (zhēn, needle) has 十 (ten) and 钉 (dīng, nail) has 丁 (nail). Visually, 钡 is wider with the shell component, while 针 and 钉 are simpler and narrower. In usage, 钡 refers to the chemical element barium, not a tool like a needle or nail.

钡 appears mainly in scientific and medical contexts, such as 钡餐 (bèi cān), a barium meal used in X-ray imaging, and 硫酸钡 (liú suān bèi), barium sulfate used as a contrast agent. It is not a common character in everyday conversation, so encountering it usually indicates chemistry or medical topics.

Common words containing 钡 include: 钡餐 (bèi cān) — Barium meal; 硫酸钡 (liú suān bèi) — barium sulfate; 钡盐 (bèi yán) — Barium salt.
