Question

a student works with a new substance. he concludes it conducts electricity very well. it has a very shiny luster. when he hammers it, it simply dents and flattens. what is the most likely substance type?
options: metal, metalloid, nonmetal

Explanation:

Metals are known for high electrical conductivity, shiny luster, and malleability (can be hammered into shapes without breaking). Metalloids have intermediate properties, and non - metals are generally poor conductors, dull (except some like graphite), and brittle. The substance here conducts electricity well, is shiny, and malleable (dents/flattens when hammered), so it matches metal properties.

Answer:

A. Metal
