What are two physical properties that make metals the ideal material from which to construct electrical wires?

Answer 1

Well, as well as #"malleability"#, metallic bonding confers #"ductility"#...

And #"ductility"# means that the material is capable of being drawn into a wire. And a second property that metallic bonding, metal ions in an electron sea, confers is electrical conductivity...and thus wires may conduct an electric current.

Metals are perfect for making electrical wires because of two physical characteristics: high electrical conductivity and ductility.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
