Form a covalent electron sharing bond.
The difference in electronegativity determines the type of chemical bonding between atoms. Metals and nonmetals often have a large difference in electronegativity, and tend to form ionic bonds, while nonmetals bonded to nonmetals tend to have smaller electronegativities and tend to form covalent bonds.
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
The electronegativity difference between nonmetals is relatively small, so such compounds are nearly always covalent. On the other hand the electronegativity difference between a metal and a nonmetal is often fairly large, so metal-nonmetal compounds are usually ionic.
An Ionic bond is one where an element gives away electrons to another, forming Ions. It usually occurs between metals and nonmetals. Another way to tell is if the electronegativity difference between the elements is greater than 2.0 then it is an ionic bond. A covalent bond is one where the elements share electrons with one another. It usually occurs between nonmetals. If the electronegativity difference between the elements is 2.0 or less it is a covalent bond.
Two elements will form ionic compound if the difference in electronegativity between the two elements is above 1.7 and two elements will form covalent compound if the difference in electronegativity between the two elements is below 1.7 Metals and non-metals will form generally ionic compounds.
The difference in electronegativity determines the type of chemical bonding between atoms. Metals and nonmetals often have a large difference in electronegativity, and tend to form ionic bonds, while nonmetals bonded to nonmetals tend to have smaller electronegativities and tend to form covalent bonds.
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.

You look up the elements involved on a periodic table, if there is a low electronegativity difference between them and if they are both nonmetals it is so. (Electronegativity decreases when you go left, increases when you go down)

Sodium electronegativity (after Pauling): 0,93 Bromine electronegativity (after Pauling): 2,96 The difference is 2,03.
Two elements will form ionic compound if the difference in electronegativity between the two elements is above 1.7 and two elements will form covalent compound if the difference in electronegativity between the two elements is below 1.7 Metals and non-metals will form generally ionic compounds.
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.
Search a table with the electronegativities of chemical elements.- electronegativity difference between the two elements is over 2: ionic bond.- electronegativity difference between the two elementsis is in the range 0 to 2: polar covalent bond.- electronegativity difference between the two elementsis near zero: nonpolar covalent bond.Generally metals form ionic bonds and nonmetals covalent bonds.For ease you see this link too.
Nonpolar bonds show a Low electronegativity difference between atoms
An electronegativity difference of less that 1.7 between the atoms
