Because they are solid and hard

Because they have mobile electrons that move freely in the lattice of positive ions

Because they are shiny and reflective

Because they are malleable

Because they are shiny and reflective

Because the layers of positive ions in the lattice can slide over one another when a force is applied

Because they conduct electricity

Because they are hard and brittle

They conduct electricity.

They react with water.

They form acidic oxides.

Their densities are low.

They are hard.

High conductivity in solid and molten states.

High conductivity in solid state, low in molten state.

Low conductivity in solid state, high in molten state.

Low conductivity in both solid and molten states.
