13 points. Dr. Suresh has another element for her students to identify. This element has a dull appearance. It is very hard, but is neither malleable nor ductile. It does not conduct heat or electricity very well, and it does not respond to a magnet. Is it most likely a metal, a metalloid, or a nonmetal?
a, metal
b, metalloid
c, nonmetal
d, There is not enough information to tell
