Exchange ring have been characterized by the property that for all a ∈ R, there exist an idempotent e ∈ aR such that (1 − e) ∈
(1 − a)R. A unit-picker is a map G that associates to every ring R a well-defined set G(R) of central units in R such that G(R) is
invariant under isomorphism of rings.
In [5] An element q in a ring R is called a G-idempotent (or quasi-idempotent [4]) if q
2 = gq for some g ∈ G or, equivalently,
g
−1
q is an idempotent for some g ∈ G. In this work we introduce the notation of G-exchange ring via G-idempotent and give some
relation betweenG-exchange ring and (strongly)-G clean ring.
