Ionic bonds are formed by electrostatic forces between ions whereas covalent bonds are formed by sharing of electrons.
The difference in electronegativity between the atoms that are bonded. A difference of more than about 1.7 indicates that the bond will be ionic. Health warning - this is only a rule of thumb.
The greater the electronegativity difference between the two bonded atoms, greater is the ionic character of the bond.
A bond between elements with a large difference in electronegativity will have the greatest ionic character. For example, the bond between a metal and a nonmetal (e.g. NaCl) will have a high ionic character compared to a bond between two nonmetals (e.g. H2O).
The bond with the greatest ionic character is typically found in compounds between elements with a large difference in electronegativity. For example, the bond in lithium fluoride (LiF) is known to have a high ionic character due to the large difference in electronegativity between lithium and fluorine.
One way to determine if a bond is ionic or covalent is to look at the electronegativity difference between the two atoms. If the difference is large (greater than 1.7), the bond is likely ionic. If the difference is small (less than 1.7), the bond is likely covalent. Additionally, ionic bonds typically form between a metal and a nonmetal, while covalent bonds form between two nonmetals.
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.

The greater the electronegativity difference between the two bonded atoms, greater is the ionic character of the bond.
Ionic bond, as the difference in electronegativity between calcium and fluorine is over 1.7
If the difference in electronegativity between the elements is greater than 2 then the bond will be ionic, if its between 1.6 and 2 then it will be ionic if one of the elements is a metal.
A bond between elements with a large difference in electronegativity will have the greatest ionic character. For example, the bond between a metal and a nonmetal (e.g. NaCl) will have a high ionic character compared to a bond between two nonmetals (e.g. H2O).
The ionic bond bond is based on electrostatic attraction between ions.The covalent bond is based on electrons sharing between two atoms.The hydrogen bond exist between two polar groups and is a weak bond.

The bond with the most ionic character among those options is NaI (sodium iodide). Ionic character increases with the difference in electronegativity between the bonded atoms. In this case, the large difference in electronegativity between sodium (a metal) and iodine (a non-metal) leads to a highly ionic bond.
PBO (lead(II) oxide) contains both ionic and covalent bonds. The bond between lead and oxygen is predominantly ionic due to the electronegativity difference, while the oxygen-oxygen bond is covalent.
