FeO is Iron(II)oxide, archaically , Ferrous oxide. Do NOT confuse with Fe2O3, which is Iron(III)oxide ; Archaically Ferric oxide. The 'iron' atom is in different oxidation states for these two compounds. NB 'Fe' is the chemical symbol for 'Iron', and comes from Latin 'Ferrum' for iron.
That is the chemical formula. The name would be iron (III) oxide, or ferric oxide in the old system.
