Question Analysis
This question involves the core formation mechanism of ionic bonds and the distinction between ionic bonds, covalent bonds, and metallic bonds. 

Key Concept Explanation
Ionic bonding involves the transfer of one or more electrons from a metal atom to a nonmetal atom. The metal loses electrons and becomes a positively charged cation, while the nonmetal gains electrons and becomes a negatively charged anion. The electrostatic attraction between these oppositely charged ions forms the ionic bond.

Option Analysis
1. Recall the ionic bond formation conditions: Requires a metal and a nonmetal, with electron transfer to form ions.
2. Evaluate each option:
Option A: Incorrect. This describes covalent bond formation. 
Option B: Correct. This matches the core mec...
