The given electron configuration is not standard notation and seems to contain typographical errors. However, interpreting it as [Ar] 4s^2 3d^10 4p^3 suggests the element is from group 5A (15) of the periodic table, as elements in this group have five electrons in their outermost p orbital, which corresponds to the configuration ending in 4p^3.
