# Electron configuration of darmstadtium
The electron configuration of darmstadtium is [Rn] 5f¹⁴ 6d⁸ 7s², written out in full as 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹⁰ 4f¹⁴ 5s² 5p⁶ 5d¹⁰ 5f¹⁴ 6s² 6p⁶ 6d⁸ 7s². Its 110 electrons fill 7 shells as 2, 8, 18, 32, 32, 16, 2, so the outermost shell holds 2 electrons. Because only a few atoms have ever been made, this configuration is a theoretical prediction.
