Since the difference between their electronegativities is less than 1.7, therefore they will form covalent bond. Also because the difference is greater than 0.5 the bond will be polar covalent. Note that these differences in electronegativity are rules of thumb and some text books and teachers will recommend different differences.
An important difference of electronegativities is a major chance for an ionic bond.

yes. If the electronegativity differnce between two atoms is greater than 1.7, then an ionic bond is formed between them. If the electronegativity differnce between two atoms is less than 1.7, then a covalent bond is formed between them.
If there is a slight electronegativity difference, the bond is a nonpolar covalent bond. If there is a large electronegativity difference, it is an ionic bond. If the difference is somewhere between, it is a polar covalent bond.
In a bond if the electronegativity is stonger in an atom then it gains a negative charge and the atom with the weaker electronegativity gains a posotive charge.

Using the Electronegativity ChartNitrogen has an electronegativity value of 3.1 whereas hydrogen has a value of 2.1. Since the difference between their electronegativities is less than 1.7, therefore they will form covalent bond. Also because the difference is greater than 0.5 the bond will be polar covalent. Note that these differences in electronegativity are rules of thumb and some text books and teachers will recommend different differences.

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.

In a bond if the electronegativity is stonger in an atom then it gains a negative charge and the atom with the weaker electronegativity gains a posotive charge.

Polar
Electronegativity differences of <0.5 indicates a nonpolar covalent bond. Electronegativity differences between 0.5 and 1.6 indicate a polar covalent bond. Electronegativity differences >2.0 indicates an ionic bond. For electronegativity differences between 1.6 and 2.0, if the bond involves a metal, it is considered to be ionic. If the bond is between two nonmetals, the bond is considered to be polar covalent. Refer to the related link below for more information.
Polar covalent bond.
If the difference in electronegativity between the metal and the non metal is above 1.7, then ionic bond is formed. If the difference in electronegativity between the metal and the non metal is below 1.7, then polar covalent bond is formed.
