How to Write 镄 (fèi) — Meaning “Fermium (Fm)”

Think of the phrase "a metal that costs a lot" because 费 means "expensive" or "cost" and fermium is a rare, expensive synthetic element. Visualize a gold bar with a high price tag to link 钅 (metal) and 费 (cost) together.

Pay attention to the proportions: the left radical 钅 is narrow, while the right part 费 is wider. A common mistake is writing the upper part of 费 as 弗 (fú) instead of the correct strokes: first horizontal, then a folded stroke, and a vertical line through the middle.

镄 (fèi) means fermium, a chemical element, and uses the metal radical with 费. 铓 (máng) means the tip of a blade and has radical 钅 with 芒 (máng). 铸 (zhù) means to cast metal and has radical 钅 with 寿 (shòu). They have different pronunciations, meanings, and right-side components.

镄 is only used in scientific contexts to refer to the element fermium (Fm), such as in chemistry textbooks or research papers about synthetic elements. It is not part of everyday vocabulary and does not appear in cultural phrases or common speech.

Common words containing 镄 include: 镄元素 (fèi yuán sù) — The element Fermium; 镄原子 (fèi yuán zi) — Fermium atom; 镄同位素 (fèi tóng wèi sù) — Fermium isotope.
