Web22 dec. 2024 · The fourth shell has 4 subshells: the s subshell, which has 1 orbital with 2 electrons, the p subshell, which has 3 orbitals with 6 electrons, the d subshell, which has 5 orbitals with 10 electrons, and the f subshell, which has 7 orbitals with 14 electrons, for a total of 16 orbitals and 32 electrons. Web28 dec. 2016 · Its not necessary that 3rd shell has to have 18 electrons for 4th shell filling up to start. The electron filling depends upon the energy levels of the orbitals. Lower energy orbitals get filled up first. Iron's configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d6. You can note from the configuration, 4s gets filled up before 3d .
