How can you determine the orbital notation of iron?
That's great, thank you! How do we determine the number of electrons in each energy level for iron?
To determine the number of electrons in each energy level for iron, we need to use the Aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels. So, for iron, we start with the first energy level which can hold a maximum of 2 electrons, then move on to the second energy level which can hold a maximum of 8 electrons, and so on.
