Abstract | A $2$-primal ring is one in which the prime radical is exactly the set of nilpotent
elements. A ring is clean, provided every element is the sum of a unit and an idempotent. Keith Nicholson introduced clean rings in 1977 and proved the following: ``Every clean ring is an exchange ring. Conversely, every exchange ring in which all idempotents are central, is clean.'' In this paper, we investigate some of the relationships among ring-theoretic properties and topological conditions, such as a $2$-primal weakly exchange ring and its prime
spectrum Spec$(R).$
