Aufbau principle. 2 Orbital filling diagrams for hydrogen, helium, and lithium. A p orbital can hold 6 electrons. What is Hunds principle Hunds principle is a rule that helps to determine how electrons are distributed in orbitals when multiple orbitals of the same energy level are available. As the energy levels increase, the electrons are located further from the nucleus, so the orbitals get bigger. 1 Find electrons of iron 2 Write electron configuration of iron 3 Draw orbital diagram of iron Let&x27;s break down each step in detail. It is the most abundant element on Earth by mass, coming in second to oxygen (32. There&39;s another way to write an electron configuration, or to draw one out, it&39;s called orbital notation. To do that we need to find the number. This process can be broken into four steps Find the electron configuration. In writing the electron configuration for Aluminium the first two electrons will go in the 1s orbital. So we have one s two, two s one for Lithium&39;s electron configuration. View this answer.
