What is the correct Lewis structure for oxygen?

Back

The correct Lewis structure for oxygen has two pairs and two single valence electrons.

Front

What difference in electronegativity (EN) values indicates a nonpolar covalent bond?

Back

A nonpolar covalent bond is most likely to form between two elements that have a difference in EN values of 0.1.

Front

What type of bond forms between Li (EN=1.0) and O (EN=3.5)?

Back

An ionic bond forms between Li and O.

Front

What difference in electronegativity (EN) values indicates an ionic bond?

Back

An ionic bond is most likely to form between two elements that have a difference in EN values of 3.

What is the correct Lewis structure for Aluminum?

Back

The correct Lewis structure for Aluminum has three single valence electrons.

Front

Define covalent bond.

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is electronegativity?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond that occurs when two atoms share electrons unequally, resulting in a partial positive and negative charge.

Front

What is the significance of the octet rule in covalent bonding?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons, achieving a stable electron configuration.

Front

How do you determine the type of bond between two elements?

Back

The type of bond can be determined by calculating the difference in electronegativity between the two elements.
