Question

in a lab experiment, students had four samples of elements. they made observations about the appearance of each sample and then proceeded to conduct three separate experiments. in the first, they found the melting point of each by holding small samples in a bunsen burner with a temperature probe. in the second, they held a conductivity probe to two separate sample sections. in the final test, they hit a small sample with a hammer.
which element is least likely to be metallic?

Explanation:

Los metales tienen una apariencia brillante, altos puntos de fusión (a excepción de mercurio), son buenos conductores de electricidad y son maleables (pueden aplastarse sin quebrarse). El elemento A no es buen conductor de electricidad y se convierte en polvo cuando se golpea, lo que no es característico de un metal.

Answer:

A. Black pellet
