Copper has four electron rings, or energy levels. The electron configuration of copper is typically represented as [Ar] 4s² 3d¹⁰, indicating that its electrons are arranged in four distinct energy levels around the nucleus. The first energy level holds 2 electrons, the second holds 8, the third holds 18, and the fourth holds 11 in total (4s² and 3d¹⁰).
