语境与语域Context & Register
混合语境：既常见于化学、能源等专业领域，也用于日常讨论氢燃料、氢气球等。通常中性偏正式，但在日常口语中也较常见。
语法说明Grammar Note
通常不可数（指元素），但指氢原子时可数。
发音与拼写Pronunciation & Spelling
These words share the -gen spelling and the unstressed /dʒən/ suffix, but their stressed vowels differ (e.g., /haɪ/ vs /ɒk/), so they do not rhyme. Be cautious of the spelling-sound mismatch.
