Question

unless otherwise instructed, you may use the periodic table in the chemistry: problems and solutions book for this question. copper (cu) is a metal, nitrogen (n) is a nonmetal, and tellurium (te) is a metalloid. which answer shows these three elements in order of decreasing electrical conductivity? ○ te, n, cu ○ cu, n, te ○ cu, te, n ○ te, cu, n

Explanation:

To determine the order of decreasing electrical conductivity, we use the properties of metals, metalloids, and nonmetals. Metals (like Cu) have high electrical conductivity, metalloids (like Te) have moderate conductivity (between metals and nonmetals), and nonmetals (like N) have very low or no electrical conductivity. So the order from highest to lowest (decreasing) conductivity should be metal (Cu) > metalloid (Te) > nonmetal (N).

Answer:

Cu, Te, N
