Each instantiation and full specialization of the std::atomic template defines an atomic type. If one thread writes to an atomic object while another thread reads from it, the behavior is well-defined (see memory model for details on data races). In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory ...

Explanation Objects of atomic types are the only objects that are free from data races; that is, they may be modified by two threads concurrently or modified by one and read by another. Each atomic object has its own associated modification order, which is a total order of modifications made to that object.
