Answer:
The type of bond that holds bronze together is a metallic bond.
Step-by-step explanation:
In metallic bonding, the atoms of the metal elements, in this case, copper and tin, share their valence electrons, forming a "sea" of delocalized electrons that are free to move throughout the structure. This results in a strong attraction between the positively charged metal ions and the negatively charged electron cloud, creating a cohesive force that holds the metal atoms together in a solid structure.
