A. The regular arrangement of metal atoms
B. The presence of ionic bonds
C. The sharing of electrons between atoms
D. The strong electrostatic forces between ions

Answer

The regular arrangement of metal atoms

Explanation

In metallic structures, the regular arrangement of metal atoms allows delocalised electrons to move freely, contributing to properties like conductivity.

Common mistake

Confusing Metallic Bonding with Simple Molecules

Students often describe metallic bonding as occurring in simple molecules rather than recognizing it as a strong attraction involving metal atoms and delocalised electrons.

Emphasize that metallic bonding is specific to metals and involves a lattice structure with delocalised electrons, unlike simple molecules which do not exhibit this type of bonding.
