I don't know the correct way to explain this type of word in English, but it's similar to the word 'specificity'. You can describe something as specific using this word. I'm looking for a similar way to use 'atomic'. My intended usage of 'atomic' here is to describe the nature of an operation in programming: To perform an operation atomically, means that this operation completes 100% without being interrupted. It means the operation is guaranteed to be complete.
When discussing the property of being atomic with my coworkers, I wish to use it somewhat like: "This gives you the guarantee of atomicity". I know that 'atomicity' isn't a word (at least according to Google), but I hope that gives you an idea of what I'm trying to do.
What is the correct way of using 'atomic' in this way? Or am I maybe going down the wrong path here?
