Here's a breakdown:

* Metallic bonds: These are a type of chemical bond that occurs between atoms of metallic elements.

* Electron Sea Model: In metals, the outermost electrons are loosely bound to the atoms and can move freely throughout the entire structure. This creates a "sea" of delocalized electrons.

* Strong attraction: The positively charged metal ions are attracted to the negatively charged electron sea, resulting in strong attractive forces that hold the metal atoms together.
