relating to atoms in science
About atoms, the very small parts that make up all chemical elements and matter.
Vzorec užití:
atomic [noun]
Častá chyba:
Learners sometimes confuse "atomic" with "nuclear" and use them interchangeably. Use "atomic" for general talk about atoms in chemistry and physics, and "nuclear" mainly for the nucleus of an atom or for energy and weapons.
Synonyma
atomic-scale (More explicit about focusing on the very small size of atoms; used mainly in technical writing.)
Antonyma
macroscopic (Describes things large enough to be seen without a microscope, the opposite scale from atomic.)

relating to nuclear weapons or energy
About nuclear power or nuclear weapons, like an atomic bomb.
Vzorec užití:
atomic [bomb/weapon/energy/explosion/test]
Častá chyba:
Learners sometimes use "atomic" when "nuclear" would sound more natural in modern English (for example, "atomic power plant" instead of the more common "nuclear power plant"). "Atomic" is now mainly kept in fixed phrases like "atomic bomb" or in historical contexts like "the atomic age."
Synonyma
nuclear (The standard modern word in this context; often replaces "atomic" in current usage except in set phrases like "atomic bomb".)
Antonyma
conventional (Describes weapons that do not use nuclear energy, the usual contrast with atomic or nuclear weapons.)

basic indivisible unit in a system
So small and basic in a system that you cannot split it into smaller useful parts.
Vzorec užití:
atomic [unit/component/element/fact]
Častá chyba:
Learners may assume this meaning always refers to physical atoms. In technical writing, "atomic" often just means "smallest useful unit" in an abstract system, not a real atom.
Synonyma
indivisible (General word meaning something cannot be divided; "atomic" emphasizes being a fundamental building block in a system.)
Antonyma
composite (Describes something made of several parts, opposite of a single atomic unit.)

4
indivisible operation in computing
In computing, done as one whole step, so it cannot stop in the middle or be seen halfway done.
Vzorec užití:
atomic [operation/transaction/update/action]
Častá chyba:
Learners may think this meaning is about atoms or size. In computing, "atomic" only means that an action cannot be broken into visible smaller steps.
Synonyma
all-or-nothing (Informal description of the same idea; "atomic" is the precise technical term.)
Antonyma
non-atomic (Technical opposite meaning an operation can be interrupted or observed in a partial state.)

5
extremely powerful or impressive
Very strong or very impressive, like a big explosion.
Vzorec užití:
atomic [performance/party/punch/bass]
Častá chyba:
Learners may assume this informal sense is common everywhere. In fact, it is relatively rare and mostly used for dramatic or creative effect. In normal speech, words like "amazing" or "powerful" are more common.
Synonyma
explosive (Similar strong and sudden feeling; "atomic" sounds more playful and exaggerated.)
Antonyma
tame (Suggests something is weak or not exciting, the opposite of "atomic" in this sense.)
