Question

Copper (Cu) is often used for electrical wiring and cooking pans. However, iron (Fe) is much more common on Earth than copper. Why might copper be used instead of iron, if iron is easier to obtain? A link to the periodic table has been provided for your use.

Answer 1

Fe has fewer valence electrons than Cu.

Fe has a lower conductivity than Cu.

The lower conductivity of Fe makes it less useful for wiring and cookware.

Fe is less malleable and ductile than Cu.

The lower malleability and ductility of Fe make it less easy to form into wires or sheets.

Step-by-step explanation:

Answer 2

thats so wrong its

Fe has fewer valence electrons than Cu.

Fe has a lower conductivity than Cu.

The lower conductivity of Fe makes it less useful for wiring and cookware.

Fe is less malleable and ductile than Cu.

The lower malleability and ductility of Fe make it less easy to form into wires or sheets.
