atom
[C/U] Both
pl: atoms
This term carries a sense of absolute minimality and fundamental structure. It evokes the image of a tiny, vibrating core surrounded by a cloud of energy, representing the building block of everything in the physical universe. In a non-scientific context, the word is used to describe an infinitesimal amount of something. It suggests a level of precision so small that it is almost invisible or negligible, often used in negative constructions to emphasize a complete lack of a quality or feeling.
Countable when referring to an individual particle in a scientific context. Uncountable when used figuratively to describe a tiny, indivisible amount of a quality or emotion.
