Front

What charge do more electronegative atoms in covalent compounds typically have?

Back

Partial negative charge.

Front

Define a lone pair in the context of covalent bonding.

Back

A pair of non-bonding electrons.

Front

What is the chemical name for HC2H3O2?

Front

What does electronegativity refer to in covalent bonding?

Back

An atom's ability to attract shared electrons in a covalent bond.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electrons between atoms.

Front

What is the octet rule?

Back

Atoms tend to form bonds until they are surrounded by eight valence electrons.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

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

Front

What is a resonance structure?

Back

Different ways of drawing the same molecule that show the delocalization of electrons.

Front

What is the significance of bond angles in molecular geometry?

Back

Bond angles determine the shape of the molecule, which affects its properties.
