Not sure about your examples but electronegativity variance is a good rule of thumb for deciding ionic from covalent bonds.
Electronegativity variance less than 1.4, generally much less, indicates a covalent bonding.
Electronegativity variance greater than 1.4 indicates ionic bonding.

Copper 2 oxide formula?
The chemical formula for copper (II) oxide is CuO. In this compound, copper is in the +2 oxidation state and oxygen is in the -2 oxidation state.
Chemical formula for copper II oxide?
The chemical formula for copper II oxide is CuO. It is a black solid compound where copper is in the +2 oxidation state.
What is the charge for CuO?
Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
Is CuO classified as a solid?
Under normal circumstances, CuSO4, or is a solid. However, it can become a liquid if it is placed in a solution.
Why are CuO and Fe2O3 soluble in water?
CuO and Fe2O3 are not soluble in water because they are both metal oxides with ionic bonds, which are generally insoluble in water. The high electronegativity of oxygen attracts the metal cations strongly, making it difficult for them to dissociate and form ions in water.
IS CuO Ionic or molecular?
CuO is an ionic compound because it is composed of a metal (copper) and a non-metal (oxygen) that are bonded together through ionic bonds.
Ionic compound name for CuO?
CuO is copper (II) oxide, also known as cupric oxide.
Is CUO covalent or ionic?
Covalent bonds are between non-metals only. Ionic bonds are between non-metals and metals. Copper is a metal and oxygen is a non-metal; therefore, Copper II oxide is ionically bonded.
Which ones in the chemical reaction 'CuO CO2---CuCO3' are ionic compounds?
CuO + CO2 -> CuCO3 CuO is copper oxide and is an ionic bond Cu(2+) and O(2-) CuCO3 is also an ionic bond, as one oxygen from copper oxide has joined with the covalently bonded carbon dioxide, CO2, to form carbonate, a polyatomic ion. Cu(2+) and CO3(2-)
Is copper II hydroxide covalent?
Copper (II) oxide, CuO is a compound containing a metal - copper, and a non-metal - oxygen. It is therefore has ionic bonding. Remember: Metal - non-metal = ionic bonding Non-metal - non-metal = covalent bonding Metal - metal = metallic bonding
Is Cuo a ionic or molcular?
The simplest description is that it is ionic, and the argument is that the difference in electronegativity causes a full transfer of electrons. It is high melting solid and certainly i not molecular. As with many metal oxides the real bonding is somewhere between ionic and covalent, and this is particularly true for metals other than those in group1 and 2. I personally do not like the categorisation of compounds into ionic and molecular. Many macro crystalline solids are covalent.
Is CuO ionic compound?
Yes, CuO is an ionic compound. It is composed of a metal (copper, Cu) and a non-metal (oxygen, O) which form an ionic bond through the transfer of electrons. Copper gives up electrons to oxygen, resulting in the formation of positively charged copper ions (Cu2+) and negatively charged oxide ions (O2-).
When copper carbonate is heated what ionic compound remains?
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
What is a compound composed only of non metals?
A compound composed only of nonmetals is called a covalent compound. These compounds are formed by sharing electrons between atoms, rather than transferring them as in ionic compounds. Examples include carbon dioxide (CO2) and water (H2O).
What ionic compound remains when copper II carbonate is heated?
When copper(II) carbonate is heated, it decomposes to form copper(II) oxide and carbon dioxide. The ionic compound that remains is copper(II) oxide, which has the chemical formula CuO.
CuO ionic or molecular?
CuCl2 is an ionic compund as it contains a non-metal element and a metal element. Copper (Cu) becomes a positive ion- it looses 2 electrons. Chlorine (Cl) becomes a negative ion- 2 cholrines gain 1 electron each.
Is copper oxide CuO a compuond or a heterogeneous mixture?
CuO is a compound. It is not a mixture.
