Unit 3 Bonding Test Review--In-Class

Front

What is metallic bonding?

Back

Metallic bonding is characterized by the delocalization of valence electrons, allowing them to move freely between positively charged cations.

Front

What is the formal charge on carbon in a neutral molecule?

Back

The formal charge on carbon in a neutral molecule is typically 0.

Front

What is the hybridization of carbon in methane (CH₄)?

Back

The hybridization of carbon in CH₄ is sp³.

Front

How is electronegativity defined?

Back

Electronegativity is the ability of an atom in a molecule to attract electrons.

Front

What hybridization does a nitrogen atom undergo in ammonia (NH₃)?

Back

A nitrogen atom undergoes sp³ hybridization in ammonia (NH₃).

Front

What is the shape of a molecule with sp³ hybridization?

Back

The shape of a molecule with sp³ hybridization is tetrahedral.

Front

What is the significance of formal charge in molecular structures?

Back

Formal charge helps determine the most stable structure of a molecule by indicating the distribution of electrons.

Front

What is the relationship between electronegativity and bond polarity?

Back

The difference in electronegativity between two atoms determines the polarity of the bond; greater differences lead to more polar bonds.

Front

What type of bond is formed between two atoms with a large difference in electronegativity?

Back

A polar covalent bond is formed between two atoms with a large difference in electronegativity.

Front

What is the geometry of a molecule with sp hybridization?

Back

The geometry of a molecule with sp hybridization is linear.
