Answer:
model of metallic bonding, Luster, Malleability, Conductivity
Step-by-step explanation:
The electron sea model is a model of metallic bonding in which cations are considered to be fixed points within a mobile 'sea' of electrons.
Luster: Metals are shiny when cut, scratched, or polished.
Malleability: Metals are strong but malleable, which means that they can be easily bent or shaped. For centuries, smiths have been able to shape metal objects by heating metal and pounding it with a hammer. If they tried this with nonmetals, the material would shatter! Most metals are also ductile, which means they can be drawn out to make wire.
Conductivity: Metals are excellent conductors of electricity and heat. Because they are also ductile, they are ideal for electrical wiring. (You can test this using some household items. Keep reading to find out how!)
