Question

Which of the following statements is most likely true for an element present in section B? It is a highly reactive metal. It is an inert gas at room temperature. It may act as an insulator or a conductor. It is a highly reactive liquid at room temperature.

Answer 1

Step-by-step explanation:

The question requires us to choose the statement that best represents the element in section B represented in tha periodic table. This is a question about the periodic table > classification of elements

To solve this problem, we'll need to take a look at the periodic table and identify some characteristics of elements represented in section B.

Comparing the image given by the question to the periodic table represented above, we can identify the region A as transition metals, region B as representing metalloids and region C as representing the halogens.

The elements that are classified as metalloids, also called semimetals, present properties that are intermediate between those of metals and nonmetals. An example of a semimetal is silicon (Si), that presents a characteristic shine from a metal, but it is also brittle as a nonmetal. Silicon is used in computers and electronic devices because its electrical conductivity is in between that of a metal (high conductivity) and a nonmetal (poor electrical conductivity)

Considering the information above and the location of the region B given by the question, we can say that the best statement to represent an element in section B is "It may act as an insulator or a conductor".
