Polar vs NonPolar Covalent Bonds

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of chemical bond where electrons are shared unequally between two atoms, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of chemical bond where electrons are shared equally between two atoms, resulting in no charge difference across the bond.

Front

What determines the polarity of a bond?

Back

The polarity of a bond is determined by the difference in electronegativity between the two atoms involved in the bond.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What type of bond is formed between sodium and oxygen?

Back

Ionic bond.

Front

True or False: The greater the difference in electronegativity, the more polar the bond.

Back

True.

Front

Which electrons are involved in chemical bonding?

Back

Valence electrons.

Front

In a covalent bond between carbon and chlorine, which atom is more electronegative?

Back

Chlorine.

Front

What does a Lewis structure represent?

Back

A Lewis structure represents the arrangement of valence electrons around atoms in a molecule.

Front

What happens to the electrons in a polar covalent bond?

Back

In a polar covalent bond, electrons are attracted more towards the more electronegative atom, creating a dipole.
