How to Write 钫 (fāng) — Meaning “Francium”

Imagine a square (方) made of shiny metal (钅) that glows because francium is radioactive. The visual of a glowing square metal helps link the shape to the element's properties. You can also think of the pinyin "fāng" sounding like "fang" of a radioactive wolf.

The left radical 钅 is written first with three horizontal strokes, then a vertical hook, and the leftmost stroke is a short horizontal. The right part 方 should be balanced — start with a dot, horizontal, then a curved hook, and the last stroke is a diagonal line through the middle. A common mistake is making the 方 too wide or not aligning the dot to the left.

钫 (fāng) means the element francium, while 针 (zhēn) means needle or pin, and 钉 (dīng) means nail. Visually, all three have the metal radical 钅, but the right side differs: 方 (square) for 钫, 十 (ten) for 针, and 丁 (nail) for 钉. They are pronounced differently and have completely different everyday uses.

钫 is a specialized character used almost exclusively in scientific contexts, such as chemistry textbooks or periodic table charts. It refers to the highly radioactive element francium, which is extremely rare and unstable. You will not encounter it in daily conversation or general reading unless studying advanced chemistry.

Common words containing 钫 include: 钫元素 (fāng yuán sù) — The element Francium; 金属钫 (jīn shǔ fāng) — Francium metal; 放射性钫 (fàng shè xìng fāng) — radioactive francium.
