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)
Cr is a transition metal element, specifically chromium. It is not considered ionic or molecular on its own.
Mg is an ionic element. It typically forms cations by losing two electrons to achieve a stable electron configuration, making it an ionic element.
Yes, FeO is connected by an ionic bond. In FeO, iron (Fe) has a positive charge and oxygen (O) has a negative charge, leading to the formation of an ionic bond between the two elements.
The element chlorine at standard temperature and pressure is molecular and has the formula Cl2.
Neither, because silicon is an element, not a compound.
Fluorine is molecular, but it is an element, not a compound.

Sulfur is a chemical element.
The element chlorine at standard temperature and pressure is molecular and has the formula Cl2.
Neither, because silicon is an element, not a compound.
Sodium chloride (NaCl) is an ionic compound.
Iron(II) oxide (FeO) forms an ionic bond. Iron loses electrons to oxygen, resulting in the formation of Fe2+ and O2- ions which are held together by electrostatic forces.
Iodine is a molecular compound because it contains two atoms of the same element chemically bonded together.
No. It is ionic. That means that Zn has given off to of its electrons to Oxygen and because of the difference in electrical charge between the to they form a binding.
Copper itself is a pure element and does not form compounds under normal conditions. However, copper can combine with other elements to form both ionic and molecular compounds depending on the elements it is bonded with.
