Answer:
The first table correctly classifies the materials.
Explanation:
In table 1, all the elements on the left side are transition metals, expect for steel. Steel is not an element, it's an alloy (Which is a combination of two or more elements).Transition metals are very good conductors of heat and electricity. The reason why transition metals make such good conductors is because their outer electrons can move freely in their atom.
The right side of table 1 correctly classifies the materials that do not conduct electricity. The reason why those materials are poor conductors is because they all have their electrons tightly bound to their atoms.
In table 2, it classifies copper has a poor conductor which is wrong. It also classifies wood as a good conductor which also wrong for the reasons I stated above.
