Which element is most likely to allow electricity to pass through it?
copper
carbon
helium
sulfur

Copper because it’s a metal

Hello,
I have attached a periodic table to allow you to further understand my answer. We know elements are categorized in groups of Metals, Nonmetals, and metalloids. Let’s analyze each element. Sulfur is a nonmetal which mean it does not conduct well and does not have a good appearance, the same applies to all the other non metals on this list, including sulfur and helium. Copper is our only answer in which it fits and electricity can pass through/conduct easily. So our answer is copper. I hope this helps you with your assignment.

Copper, silver, aluminum, cobalt, chromium, mercury 

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
