Answer:

Lustrous, malleable, ductile, electrically conductive

Explanation:

The metallic lattice consists of layers of metal cations being held together by a "sea" of their delocalised electrons. Here's a diagram to illustrate this:

Lustrous- The delocalised electrons vibrate when hit by light, producing their own light.
Malleable/ductile- Metal sheets/ions are able to roll past each other into new positions, without the metallic bonds breaking apart.
Electrically conductive- delocalised electrons are able to move around and carry a current.
