Question

Which of the following lists the elements in order of increasing conductivity?

O TI, Te, He
O Tl, He, Te
O Te, He, Tl
O He, Te, Tl

Answer 1

The order of increasing conductivity is Te, He, Tl.

Step-by-step explanation:

The correct answer is Te, He, Tl.

Conductivity is a measure of how well a substance conducts electricity. In general, metals are good conductors of electricity, while nonmetals are poor conductors. Among the given elements, Te (tellurium) is a metalloid, He (helium) is a nonmetal, and Tl (thallium) is a metal.

Since metals have high conductivity compared to nonmetals, the order of increasing conductivity is Te (the highest), He, and Tl (the lowest).
