The electronegativity can be defined as the tendency of an atom to attract an electron.
There are three rules of Bonding:-
The third rule is governed by critical electro-negativity difference from Pauling's expression for the ionicity fraction of a bond.
For more insight on Electro-negativity difference you can search Pauling's Scale or study the related link below.
One way to predict if a bond is ionic or covalent is to compare the electronegativities of the atoms involved. If there is a large difference in electronegativity, the bond is likely ionic; if there is a small difference, the bond is likely covalent. Another approach is to look at the types of elements involved - ionic bonds typically form between a metal and a nonmetal, while covalent bonds form between nonmetals.
If a compound is composed of nonmetal elements, it is likely covalent. Covalent compounds share electrons between atoms to form bonds. In contrast, ionic compounds are formed when a metal transfers electrons to a nonmetal, resulting in the attraction between positive and negative ions. The greater the difference in electronegativity between the elements, the more likely the compound is ionic.
Ionic bonds are most likely to occur between a metal and a non metal due to the general difference in electronegativity. Examples include sodium chloride, iron oxide, etc. In these bonds, electron(s) are typically transferred from the metal to the non-metal.
AI2S3 is an ionic compound. The presence of the metal atom Al and the nonmetal atom S indicates that it is likely to form ionic bonds due to the electronegativity difference between the two types of atoms.
Elements with a large difference in electronegativity are most likely to form ionic bonds. This includes combinations of a metal with a nonmetal, where the metal tends to lose electrons while the nonmetal tends to gain electrons to achieve a full outer shell.

Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.
If a compound is composed of nonmetal elements, it is likely covalent. Covalent compounds share electrons between atoms to form bonds. In contrast, ionic compounds are formed when a metal transfers electrons to a nonmetal, resulting in the attraction between positive and negative ions. The greater the difference in electronegativity between the elements, the more likely the compound is ionic.
The elements to the very left of the table are likely to bond to the elements to the very right of the table. It all depends on the amount of electrons are in the outer shell of the element. A compound of two elements favor filling the outer shell with a total of 8 electrons.
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.
d magnesium and oxygen. Magnesium is a metal and oxygen is a nonmetal, so they are more likely to form an ionic bond due to the large difference in electronegativity between the two elements. Ionic bonds typically form between a metal and a nonmetal.

A covalent bond forms when atoms share electrons. If two atoms have similar electronegativity values (general rule of thumb is if their electronegativity values is less than 1.67) than the two atoms are more likely to share electrons. This tends to happen between two non-metals. Ionic bonds form between two atoms with electronegativity value differences greater than 1.67. They involve a transfer of electrons. This occurs between a metal and nonmetal.
An ionic compound is when the an atom gives away or receives electrons to become stable. A covalent compound is when the atoms share electrons to become stable.It is a Ionic bond because it is between nonmetals and metal
The difference in electro-negative between the two atoms is below 0.4. Atoms are both from the nonmetal groups.
