If the electronegativity difference between two atoms is less than 1.7, then a covalent bond is formed between the two atoms.
If the difference in the electronegativity between two atoms is more than 1.7, then the bond is ionic and if the difference is below 1.7, then the bond is covalent.
If the EN difference is greater than 4 and less than 1.7, the bond is polar covalent.

Hydrogen bonding exists between hydrogen and oxygen in water, becuase of the huge electronegativity difference between oxygen and hydrogen. This arises, due to the huge electron affinity of oxygen. Such interaction is not possible between carbon and hydrogen, as athe carbon is not as electronegative as oxygen.
A negative charge exists because of the electronegativity of oxygen.

The greater the electronegativity, the stronger an oxidant that element will be. The lower its electronegativity, the stronger a reducing agent it will be.
A "spectrum" of sorts exists when it comes to bonding. Ionic is an one end and covalent is at the other. Electronegativity difference between constituent elements is what determines a compound's placement on this bonding spectrum. Cesium fluoride, for instance, has the greatest electronegativity difference of any metal-nonmetal combination. Therefore, CsF is very near the ionic extreme of the bonding spectrum. However, even this formula unit will exhibit tiny amounts of covalent character based upon the random motion of electrons.
Covalent bond exists between a carbon atom and a chlorine atom.
Single 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.
