Metals conduct electric current easily because _______.

• positive metal ions freely move the electrical current

• metals are so dense that electric current has to flow through it

• the structure of metals are rigid and brittle, which allows current to flow freely

• the valence electrons in a metal can move freely among the atoms

A(n) _______ is a mixture of two or more elements, at least one of which is a metal.

• alloy

• super conductor

• crystalline solid

• amorphous solid
