Structure of Metals and Alloys - Pre

What characteristic of metals makes them good electrical conductors?

• They have mobile valence electrons.

• They have mobile protons.

• They have mobile cations.

• Their crystal structures can be rearranged easily.

Why do metals conduct electricity?

• They are shiny

• The electrons are held tightly within the lattice

• The valence electrons can move from ion to ion

• The electrons are shared between two metal ions
