How 鈾 is built
Phono-semantic (sound + meaning) character. Metal.
釒 gives the meaning and 由 hints at the sound.
Radical: 釒 (gold), shared by 135 characters on this site.
How to remember 鈾
The metal radical 釒 on the left tells you this is a metal, and 由 (yóu) on the right gives the sound. Think of uranium as the metal that energy comes "from" (由 means "from").
鈾 is the traditional form, and mainland China writes it 铀. It appears mostly in science, energy, and news contexts. Example: 浓缩铀 (nóngsuōyóu) enriched uranium, as in 他们在生产浓缩铀。(Tāmen zài shēngchǎn nóngsuōyóu.) They are producing enriched uranium.
Common mistake: Learners often confuse 由 with 田 (tián) or 甲 (jiǎ). In 由 the middle stroke pokes out the top, so 鈾 should not be written as 鈿 (tián/diàn) or 鉀 (jiǎ, potassium). Also note the tone: mainland Mandarin says yóu (second tone), while Taiwan says yòu (fourth tone).
