When electrons are shared amongst all atoms in a structure, the resulting bond is a(n) ________ bond.

• A. ionic
• B. metallic
• C. covalent
• D. hydrogen

Answer: (B)

Verified step by step guidance

1. Understand the types of chemical bonds: ionic bonds form when electrons are transferred between atoms, covalent bonds form when electrons are shared between specific atoms, and hydrogen bonds are weak interactions involving hydrogen and electronegative atoms.
2. Recognize that when electrons are shared not just between two atoms but are delocalized and shared among many atoms in a structure, this is characteristic of metallic bonding.
3. Recall that metallic bonds involve a 'sea of electrons' that are free to move around, which explains properties like electrical conductivity and malleability in metals.
4. Identify that the problem describes electrons being shared amongst all atoms in a structure, which matches the definition of a metallic bond.
5. Conclude that the correct type of bond described is a metallic bond.
