Polarity

Front

What does the symbol above F in a Lewis structure indicate?

Back

Electrons are more attracted to F than H.

Front

In a polar covalent bond, how are electrons shared?

Back

Unequally.

Front

How can you determine if a molecule is polar or non-polar?

Back

Analyze the symmetry and electronegativity differences in the molecule.

Front

What characterizes a nonpolar covalent bond?

Back

Electrons are shared evenly.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a bond.

Front

What is a polar molecule?

Back

A molecule with a net dipole moment due to the presence of polar bonds.

Front

What is a nonpolar molecule?

Back

A molecule that does not have a net dipole moment, often due to symmetrical charge distribution.

Front

What is the significance of the dipole moment in a molecule?

Back

It indicates the polarity of the molecule and the distribution of electrical charge.

Front

How does the difference in electronegativity affect bond polarity?

Back

A greater difference in electronegativity between two atoms leads to a more polar bond.

Front

What is a cation?

Back

A positively charged ion that has lost one or more electrons.
