An example provided in Slater's original paper is for the iron atom which has nuclear charge 26 and electronic configuration 1s22s22p63s23p63d64s2.

He listened to the soft sigh of the swirling, iridescent iron atoms.

It was a skeleton of iron atoms from which most of the energy had been extracted.

Small rows of iron atoms, they found, spontaneously formed an antiferromagnet.

Here the vibrations of the iron atoms are responsible for this transport.

The iron atom can also bind to other molecules such as carbon monoxide.

The iron atom is also coordinated to His335, His371, and Glu341.

During a charge, the iron atom in the center of the octahedron has a high spin state.

Due to its 4 unpaired electrons in 3d shell, an iron atom has a strong magnetic moment.

Jim Swenson Not all of the 3 iron atoms has the same "formal charge".
