The noble gas notation for Iron (Fe) is [Ar]4s2 3d6.
sublevel notation shows the electrons and their spins within each orbital. For example the 1s2 electrons would have one arrow pointing up and one arrow pointing down.
[Ar]4s^2 3d^6
These symbols are:5626U and Fe-56.
CARBON
It refers to numbers of electrons in the 2p sublevel.
i think your thinking of the notation? iron 59 notation is Fe-59
Orbital notation shows how the electrons are arranged in the orbitals of the sublevels. Electron configuration shows only how many electrons are in each sublevel.

There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
It enters the f sublevel.
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.

There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
Multiply the orbitals in that sublevel by 2. The s sublevel has one orbital and can contain 2 electrons. The p sublevel has three orbitals and can contain 6 electrons. The d sublevel has five orbitals and can contain 10 electrons. The f sublevel has seven orbitals and can contain 14 electrons.
