Tami is doing experiments on three different unknown solids. She understands that treating them in different manners might result in changes to their bonding, and these changes may help her identify unknowns. She treats samples of each solid four different ways: heating them, letting them cool, shining bright light on them, and hitting them once with a hammer. The chart shows what happened to each sample.Based on how they each acted in the trials, which substance(s) would most likely be metallic?

Which shows two structures that are made mostly of metal?
