Later in 1878, a Swedish chemist, Per Teodor Cleve independently discovered the element while he was working on erbia earth (erbium oxide). We'll need to know how many sublevel is present in each energy level, and in turn, how many electrons each sublevel can accommodate. The third electron in lithium has to go into the second level because the 1s is . In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal . 8600 Rockville Pike, Bethesda, MD, 20894 USA.
