Electronegativity and Bond Polarity

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What type of bond is formed when the electronegativity difference between two atoms is between 0.5 and 1.8?

Back

A polar covalent bond is formed.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in partial charges.

Front

How does electronegativity affect bond polarity?

Back

The greater the difference in electronegativity between two atoms, the more polar the bond will be.

Front

Which element is the most electronegative?

Back

Fluorine (F) is the most electronegative element.

Front

What is the trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period from left to right and decreases down a group.

Front

How can you determine the polarity of a bond using electronegativity values?

Back

By comparing the electronegativity values of the two atoms involved in the bond.

Front

What is the electronegativity difference for an ionic bond?

Back

An ionic bond typically has an electronegativity difference greater than 1.8.

Front

Arrange the following elements in order of increasing electronegativity: N, O, B.

Back

B < N < O.
