Covalent/ Polar/ Non-polar Review

Front

What is a polar molecule?

Back

A molecule that has a partial positive end and a partial negative end due to unequal sharing of electrons.

Front

What is a nonpolar molecule?

Back

A molecule in which the electrons are shared equally, resulting in no partial charges.

Front

How can you identify a polar molecule?

Back

Look for a difference in electronegativity between the bonded atoms and the presence of a molecular dipole.

Front

What does a lowercase delta plus (δ+) signify?

Back

It indicates a partial positive charge on an atom.

Front

What does a lowercase delta minus (δ–) signify?

Back

It indicates a partial negative charge on an atom.

Front

What type of bond is formed when two atoms of the same nonmetal element bond together?

Back

A nonpolar covalent bond.

Front

What is electronegativity?

Back

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

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while nonpolar covalent bonds involve equal sharing.

Front

What is an ionic bond?

Back

A bond formed when electrons are transferred from one atom to another, resulting in charged ions.

Front

What is a dipole moment?

Back

A measure of the separation of positive and negative charges in a molecule.
