In CuO the oxidation state of Cu is +2 and is called cupric oxide, or copper-II oxide (do NOT pronounce as dioxide).
In Cu2O the oxidation state of Cu is +1 and is called cuprous oxide, or copper I oxide or di-copper oxide.
Cu0
Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
hydrogen is partially positive and oxygen is partially negative so your answer is oxygen
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
No, hydrogen bonding occurs in covalent compounds in which hydrogen is bonded to nitrogen, oxygen, or fluorine. These elements will pull electrons towards them getting a partial negative charge and giving hydrogen a partial positive charge.The actual hydrogen bonding occurs when the partial positive charge on one such molecule is attracted to the partial negative charge on another.Technically it isn't a type of bond.
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
In most compounds, the nitrogen in NH2 has a partial negative charge while the hydrogen each carry a partial positive charge. It can also exist as the Amide ion with a full negative charge.
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
Selenium form anions.
Selenium fluoride bond is polar because fluorine is more electro-negative than selenium. Hence the shared paired of electrons are more towards fluorine giving fluorine a partial negative charge and selenium a partial positive charge.
hydrogen is partially positive and oxygen is partially negative so your answer is oxygen
positive charge
Interhalogens like ClF or ClF3. Acids such as HClO, HClO2, HClO3, HClO4.
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
This is a polar molecule.

In CuO, as oxygen is he most electronegative among the non metals.
One end of a molecule or atom has a partial negative charge and the other end has a partial positive charge.
