In computing:
- A synonym for valenceValence (chemistry)In chemistry, valence, also known as valency or valence number, is a measure of the number of bonds formed by an atom of a given element. "Valence" can be defined as the number of valence bonds...
. - Atomicity, an element of orthogonalityOrthogonalityOrthogonality occurs when two things can vary independently, they are uncorrelated, or they are perpendicular.-Mathematics:In mathematics, two vectors are orthogonal if they are perpendicular, i.e., they form a right angle...

In computing:
- Atomicity (database systems), a property of database transactions which are guaranteed to either completely occur, or have no effects.
- Atomicity (programming), in computer science, especially parallel algorithms, an operation appears to occur at a single instant between its invocation and its response.
- Atomicity, a property of an S-expressionS-expressionS-expressions or sexps are list-based data structures that represent semi-structured data. An S-expression may be a nested list of smaller S-expressions. S-expressions are probably best known for their use in the Lisp family of programming languages...
