Answer
B. Metal atoms
Explanation
Metallic bonding is a term describing the type of atomic bonding predominantly occurring in metals. It's responsible for many of their distinctive properties, such as their physical strength, luster (since they are good reflectors of light), conductivity (electrical and thermal), and malleability. This type of bonding involves the sharing of free electrons among a lattice of positively charged ions, where the electrons are delocalized and free to move throughout the material. The option that mentions "metal and non-metal atoms" describes ionic bonding, not metallic bonding. Similarly, non-metal atoms and noble gases do not experience metallic bonding. Non-metal atoms usually participate in covalent bonding, while noble gases are inert and do not usually form bonds due to their full valence electron shells. Therefore, metallic bonding refers to the bonding between metal atoms only.
