BONDING

Positive ions: Metal atoms lose outer electrons and stay in a fixed grid.

Free electrons: Electrons float freely between the ions like a liquid or a sea.

Strong pull: The positive ions and negative electrons pull on each other to lock the metal together.

Electricity: Free electrons move fast to carry electric current.

Heat: Moving electrons pass heat quickly through the metal.

Malleability: Ions slide past each other without breaking the bond when hit. [1]

This “sea of electrons” explains why metals can conduct an electric current...electrons added at one end of the metal repel nearby electrons, pushing electrons through the metal wire to the other end.
