Electronegativity Difference

Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is the significance of electronegativity difference in bonding?

Back

The electronegativity difference between two atoms determines the type of bond formed: ionic, polar covalent, or nonpolar covalent.

Front

What type of bond is formed with an electronegativity difference of 2.0?

Back

Ionic bond.

Front

What type of elements typically form ionic bonds?

Back

Metals and nonmetals.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is formed when two atoms share electrons equally, typically with an electronegativity difference of less than 0.4.

Front

What is a polar covalent bond?

Back

A polar covalent bond is formed when two atoms share electrons unequally, typically with an electronegativity difference between 0.4 and 1.7.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom donates an electron to another atom, resulting in the formation of charged ions, typically with an electronegativity difference greater than 1.7.

Front

What is the electronegativity difference for a nonpolar covalent bond?

Back

Less than 0.4.

Front

What is the electronegativity difference for a polar covalent bond?

Back

Between 0.4 and 1.7.

Front

What is the electronegativity difference for an ionic bond?

Back

Greater than 1.7.
