LetRbe an associative ring with identity. An elementx∊Ris said to be weakly clean ifx=u+eorx=u−efor some unituand idempotenteinR. The ringRis said to be weakly clean if all of its elements are weakly clean. In this paper we obtain an element-wise characterization of abelian weakly clean rings. A relation between unit regular rings and weakly clean rings is also obtained.
