lower melting points and greater conductivity than nonmetals. lower conductivity and lower density than nonmetals. higher density and lower melting points than nonmetals. greater conductivity and higher melting points than nonmetals.
I gave my students this multiple choice question: In a comparison of metals to nonmetals, metals tend to have

Only one answer is correct among these 4 choices:
- lower melting points and greater conductivity than nonmetals.
- lower conductivity and lower density than nonmetals.
- higher density and lower melting points than nonmetals.
- greater conductivity and higher melting points than nonmetals.

Could you tell me which one is correct?

greater conductivity and higher melting points than nonmetals.
