What is a bond pair in chemical bonding?

Back

A bond pair refers to a pair of electrons that are shared between two atoms to form a covalent bond.

Front

What is a lone pair in chemical bonding?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

What stabilizes negative and positive ions?

Back

Negative and positive ions are stabilized by electrostatic attraction.

Front

What types of hybridization can carbon undergo?

Back

Carbon can undergo sp³, sp², and sp hybridization.

Front

Define hybridization in the context of chemical bonding.

Back

Hybridization is the mixing of atomic orbitals to form new hybrid orbitals suitable for the pairing of electrons to form chemical bonds.

Front

What is the significance of formal charge in molecular structures?

Back

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

Front

Explain the concept of electrostatic attraction.

Back

Electrostatic attraction is the force that draws together positively and negatively charged ions or particles.
