'Electric Earth' Could Explain Planet's Rotation

FeO has not been Ferrous Oxide in many years.

As of the IUPAC Redbook 2005, the preferred name would be "Iron(II) Oxide", however the name "Iron Monoxide" is a valid stoichiometric name for the substance.

The classic name "Ferrous Oxide" is no longer considered acceptable. I quote from Table III's second definition of the suffix "-ous":

Ending formerly added to stems of element names to indicate a lower oxidation state, e.g.
ferrous chloride, cuprous oxide, cerous hydroxide. Such names are no longer acceptable.

The "-ous" suffix is still permitted as part of acid names like "seleninous acid", or "arsorous acid".
