文法句型

atomic + noun (bomb / power / weapon / energy)

用法筆記

Mostly fixed compounds: atomic bomb, atomic energy, atomic power, atomic weapon, atomic reactor. In neutral technical writing, 'nuclear' is now more common; 'atomic' often carries Cold-War or weapons overtones.

常見錯誤

The lamp uses atomic energy from a battery.
The lamp uses electricity from a battery.
💡'atomic energy' means power from splitting atoms, not ordinary electricity.

老師把課程拆成幼童也跟得上的最小步驟。

atomic + steps (extended size sense)

同義詞
  • indivisible

    plain word for 'cannot be split'

  • elementary

    the most basic kind, with nothing simpler beneath

  • minute

    stresses extremely small size, not indivisibility

反義詞

文法句型

atomic + noun (unit / piece / level)

用法筆記

Mostly found in technical writing about computing, databases, and physics, where it stresses that a thing cannot be split. Outside those fields it sounds bookish or metaphorical.

常見錯誤

Hiro is atomic in size.
Hiro is tiny.
💡for ordinary 'small', use 'tiny' or 'minute'; 'atomic' suggests something that cannot be divided further.
