WebThe single electron is assigned to the 1s sublevel, the lowest-energy sublevel in the lowest-energy level. Therefore, the electron configuration of hydrogen is written: For helium … WebNov 17, 2015 · The number of orbitals you get per energy level can be found using the equation. #color(blue)("no. of orbitals" = n^2)# Since each orbital can hold amaximum of two electrons, it follows that as many as . #color(blue)("no. of electrons" = 2n^2)# In this case, the second energy level holds a total of #"no. of orbitals" = n^2 = 2^2 = 4# orbitals.

WebAug 19, 2024 · The 1s subshell can hold a maximum of 2 electrons, so the electron configuration for a lithium atom, which has three electrons, cannot be 1s 3. Two of the lithium electrons can fit into the 1s subshell, but the third electron must go into the second shell and the lower energy orbital, which is the 2s orbital. cow vagina meal
