Ionic bonds are typically described as

• A. Very strong, require a large amount of energy to break
• B. Weak and easily broken
• C. Covalent sharing of electrons
• D. Metallic bonding

Answer: (A)

Ionic bonds come from strong electrostatic forces between oppositely charged ions arranged in a crystal lattice. Each ion is held by the attraction to many neighboring ions in three dimensions, which creates a large amount of energy needed to separate them—high lattice energy. That is why ionic compounds typically have high melting points and are quite hard to break apart. This description wouldn’t fit a bond that’s weak and easily broken, nor would it describe covalent sharing of electrons or metallic bonding, which involve different types of connections: covalent bonds share electrons between specific atoms, and metallic bonding involves a lattice of positive ions in a sea of delocalized electrons.
