Which statement describes the valence electrons in ionic bonds?

• A. Valence electrons are transferred from one atom to another.
• B. Valence electrons are shared equally between atoms.
• C. Valence electrons are shared unequally, creating partial charges.
• D. Valence electrons are delocalized over a lattice of metal atoms.

Answer: (A)

Verified step by step guidance

1. Understand the concept of valence electrons: Valence electrons are the outermost electrons of an atom and are involved in forming chemical bonds.
2. Recognize the nature of ionic bonds: Ionic bonds are formed when atoms transfer valence electrons to achieve a full outer electron shell, typically between a metal and a non-metal.
3. Identify the process of electron transfer: In ionic bonding, valence electrons are transferred from one atom (usually a metal) to another atom (usually a non-metal), resulting in the formation of ions.
4. Differentiate ionic bonds from covalent bonds: Unlike covalent bonds where electrons are shared, ionic bonds involve the complete transfer of electrons, leading to the formation of charged ions.
5. Consider the options given: Evaluate each statement based on the understanding of ionic bonds and identify that the correct description involves the transfer of valence electrons from one atom to another.
