Regents Chemistry Bonding Review

Front

What is the electron configuration of Neon (Ne)?

Back

1s² 2s² 2p⁶

Front

What type of bond is formed when two atoms share six electrons?

Back

A triple bond, as seen in nitrogen (N₂).

Front

What property causes hexane and water to separate into two layers?

Back

Molecular polarities; hexane is nonpolar and water is polar.

Front

Which bond is the most polar: H-O, F-F, C-O, or N-H?

Back

H-O is the most polar bond.

Front

Describe the polarity of a CH₄ molecule.

Back

CH₄ is symmetrical and nonpolar.

Front

What is a polar molecule?

Back

A molecule with a net dipole moment due to the presence of polar bonds.

Front

What is a nonpolar molecule?

Back

A molecule that has no net dipole moment, often due to symmetrical charge distribution.

Front

Define electronegativity.

Back

The ability of an atom to attract electrons in a chemical bond.

Front

What is the significance of the octet rule in bonding?

Back

Atoms tend to bond in a way that gives them eight valence electrons, achieving stability.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electron pairs between atoms.
