The Pauling electronegativity of O is 3,44.
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.

You think probable to electronegativity.
To calculate the electronegativity for water (H2O), you don't directly calculate a singular value for the molecule itself, but rather consider the electronegativities of the individual atoms involved. Oxygen (O) has an electronegativity of about 3.44 (on the Pauling scale), while hydrogen (H) has an electronegativity of about 2.20. The difference in electronegativity between oxygen and hydrogen contributes to the polar nature of the water molecule, with oxygen being partially negative and hydrogen being partially positive. This difference is approximately 1.24, indicating a significant polar bond.

The electronegativity difference in Na2O is calculated by finding the difference between the electronegativity values of the two elements. Sodium (Na) has an electronegativity of approximately 0.93, and oxygen (O) has an electronegativity of approximately 3.44. Therefore, the electronegativity difference in Na2O is 3.44 - 0.93 = 2.51.
Ba and O are unlikely to form a covalent bond because they have a large electronegativity difference. Ba is a metal with a low electronegativity, while O is a nonmetal with a high electronegativity. This large electronegativity difference makes it more favorable for them to form an ionic bond rather than a covalent bond.

The electronegativity difference in C2H5OH (ethanol) is between carbon (C) and oxygen (O). The electronegativity of carbon is around 2.55, while oxygen is around 3.44, resulting in an electronegativity difference of about 0.89. This polarity contributes to the overall chemical properties of ethanol.
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
The electronegativity difference between sulfur (S) and oxygen (O) is 0.5. Oxygen is more electronegative than sulfur, meaning it has a greater ability to attract electron density towards itself in a covalent bond.
No. One way to tell is that Ba and O are on opposite sides of the periodic table, and Ba is a metal and O is a nonmetal. We can also determine the difference in electronegativity. A difference of >1.6 is generally considered as ionic. The electronegativity of Ba is 0.89 and of O is 3.44. 3.44 - 0.89 = 2.55, so the bond is ionic.

Definitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegativity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4. Not even close! The further apart on the periodic table two elements are, the greater the electronegativity difference. Electronegativity GENERALLY increases going up and to the right on the table. There are, however, some cases in which exceptions can be noted, but they are not too common.
They share electrons. Atoms of the same or similar electronegativity will share electrons, and two atoms of the same type will of course have the same electronegativity. Also, two atoms joined together form a molecule, not an atom.
C-O is more polar than C=O because C=O has another pi bond in addition to the sigma bond. This would chip away at oxygen's electron density because it requires oxygen to share a part of its electrons to make the pi bond. C-O on the other hand has no such restrictions.
It means their electronegativity is equal and they are likely to be diatomic in nature. O=O, An oxygen-oxygen bond for example. Otherwise it means the two atoms ( or more ) are so close in electronegativity that there is no polarity on the molecule. Usually nonmetal to nonmetal.
The electronegativity of O₂ (oxygen gas) is around 3.44 on the Pauling scale. Oxygen is considered a highly electronegative element, meaning it has a strong tendency to attract electrons towards itself when forming chemical bonds.
