Copper (Cu), Phosphorus (P), and Iodine (I) are elements found on the periodic table as shown below.

Tests involving these three elements would show that --

• Iodine (I) is malleable and conducts electricity.

• Copper (Cu) is malleable and conducts electricity.

• Phosphorus (P) is malleable and Copper (Cu) conducts electricity.

• all three elements are malleable but do not conduct electricity.
