U6L5 - Pre Flashcard - Electronegativity and Polarity

Front

What is Electronegativity?

Back

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

Front

Order the types of bonds based on the charge of their molecules from lowest to greatest.

Back

Nonpolar Covalent -> Polar Covalent -> Ionic.

Front

In a polar covalent bond, where do the electrons gather?

Back

The electrons gather around the atom with the Greatest Electronegativity.

Front

True or False: If bonds are polar, asymmetrical molecules are polar and symmetrical molecules are nonpolar.

Back

True.

Front

What determines the polarity of a bond?

Back

The difference in the electronegativities of the two atoms.

Front

Which type of bond has partial charges?

Back

Polar Covalent bonds have partial charges.

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, leading to partial charges.

Front

What is an Ionic bond?

Back

An Ionic bond is a type of bond formed when one atom transfers electrons to another, resulting in charged ions.

Front

What is the significance of molecular symmetry in determining polarity?

Back

Molecular symmetry can determine if a molecule is polar or nonpolar; symmetrical molecules tend to be nonpolar.
