Front

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

Back

Electrons are more attracted to F than H.

Front

What shape do molecules with an expanded octet and no lone pairs on the central atom exhibit?

Back

Trigonal bipyramidal.

Front

Is this a correct dot diagram for oxygen (O)? (True/False)

Back

False.

Front

What is the term for pairs of electrons that do not participate in bonding?

Back

Lone pair.

Front

How many unshared pairs of electrons will a pyramidal molecule have on its central atom?

Back

1.

Front

What is the definition of molecular geometry?

Back

The three-dimensional arrangement of atoms in a molecule.

Front

What is polarity in a molecule?

Back

Polarity refers to the distribution of electrical charge over the atoms in a molecule.

Front

What is the VSEPR theory used for?

Back

To predict the geometry of individual molecules based on the repulsion between electron pairs.

Front

What is an expanded octet?

Back

An expanded octet occurs when a central atom has more than eight electrons in its valence shell.

Front

What is a lone pair of electrons?

Back

A pair of valence electrons that are not shared with another atom.
