Electronegativity is the ability of an atom to attract electrons (or electron density) to itself. The bonds you're talking about are ionic, polar covalent and pure covalent.
In ionic bonds one atom (the anion) hogs the electrons, so the higher the difference in EN the more likely it is ionic. Salts, eg NaCl, are ionic.
In pure covalent bonds the electrons shared are shared equally between the two atoms. The smaller the difference in EN the more likely it is pure covalent. Oxygen gas, O2, shares a pure covalent bond.
In between the two exist the polar covalent bonds. Their electronegativity is between pure covalent and ionic. They share their electrons however are slightly unequal. Water has polar covalent bonds.
Exact numbers differentiating the three vary from place to place so it is best to ask your professor what they accept.
A covalent bond occurs when there is a large difference in electronegativity between two atoms for example. Fluorine is very electronegative (as it is a non metal) and Hydrogen is not as electronegative. in fact there is a large difference in the electronegativity values. Therefore, a covalent bond occurs.
The type of bond is determined by the difference in electronegativity of the atoms.
Most of the time the bond between a metal and a nonmetal is ionic. However, there are some exceptions, such as BeCl2, which is covalent. The difference in electronegativity determines what kind of bond will form. Metals and nonmetals with a difference in electronegativity of >1.6 are considered to have an ionic bond.
When atoms in a covalent bond share electrons equally, the bond is said to be nonpolar. This occurs when the electronegativity difference between the atoms is small or negligible.
The most significant intermolecular force in NH3 is hydrogen bonding. This occurs due to the large electronegativity difference between nitrogen and hydrogen, creating a strong dipole-dipole interaction.
Answer The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have The magic number is 1.7 , if electronegativity (EN) difference is less than 1.7 then it is covalent. if it is more, then its ionic bond.
Standardizing a value occurs by determining the difference between the value.

A bond based only on electronegativity is an ionic bond. This type of bond occurs between atoms with a large difference in electronegativity, resulting in the transfer of electrons from one atom to another, creating charged ions that are held together by electrostatic forces.
An ionic bond. It occurs when one atom transfers electrons to another due to their significant difference in electronegativity. This results in the formation of positive and negative ions that are attracted to each other by electrostatic forces.
Yes, providing that the difference in electronegativity between the two atoms is 0-0.4 A bond between two of the same atoms will be nonpolar because there is no difference in electronegativity. But atoms of different elements can have the same or similar electronegativities, resulting in a nonpolar bond.
The type of bond is determined by the difference in electronegativity of the atoms.
It depends on the difference in electronegativity between the two atoms. If the EN difference between two atoms is less than 0.5,the bond is nonpolar covalent. If the EN difference between the two atoms is between 0.5 and 1.6, the bond is polar covalent. If the EN difference between the atoms is greater than 2.0, the bond is ionic. If the EN difference is between 1.6 and 2.0, and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.

A nonpolar covalent bond between two atoms of the same element occurs when they have the same electronegativity, leading to equal sharing of electrons. This results in a symmetrical distribution of charge, making the bond nonpolar.
