When one speaks of a complex molecule like a heme (heme a, for instance, is C49H56O6N4Fe) one doesn't talk about their electron configuration. Electron configurations are usually left to individual elements and possibly their ions.
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration of curium is [Rn]5f7.6d1.7s2.
