Iron (II) oxide.
the optical system of a microscope is the objectives
magnisum oxide
This is not a true compound but is mixture of Ammonium fluoride and Hydrogen fluoride , NH4F . HF
The correct name is mercury(II) sulfide.
You have the formula and symbols wrong but it is probably nickel acetate.
ferrous oxide -or- iron(II) oxide
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.
FeO is not a nonmetal; it is a compound composed of iron (a metal) and oxygen (a nonmetal).
The name of the compound iron II and oxygen (FeO) is iron(II) oxide - the correct name after the inorganic chemistry nomenclature of IUPAC - or ferrous oxide.
Iron Oxide Its actually Iron(ii) Oxide there is no such thing as iron oxide.
2 FeO
Feo Aladag's birth name is Feodora Schenk.
The compound FeO is formed by two different elements: iron (Fe) and oxygen (O). In this compound, iron has a +2 oxidation state, while oxygen has a -2 oxidation state, resulting in a neutral compound.
The compound FeO is actually named iron(II) oxide. This is because the iron in FeO is in the +2 oxidation state, so it is referred to as iron(II) to indicate the charge of the ion. The Roman numeral is used to specify the oxidation state of the metal ion in the compound.
First of all 'FeO' is NOT an element. It is a compound composed of two elements. The elements being iron(Fe) and oxygen(O). Next, you appear to misunderstand between 'Ionic' and 'molecular'. Any substance is a composed of two or more atoms is a molecule. The method of combination of these atoms can be either 'Ionic' or 'covalent'. Iron(II) Oxide (FeO) is an ionic molecule (compound). Fe^(2+)(aq) + O^(2-)(aq) = FeO(s)
iron
The oxidation number of Fe in FeO (iron oxide) is +2. This is because oxygen typically has an oxidation number of -2, and in a neutral compound like FeO, the oxidation numbers must balance out to zero.
