Considering the type of element represented by each of the following, which of the elements below is most likely to have the highest electrical conductivity?A.CaB.SiC.SeD.I

The electrical conductivity of an element is largely determined by the number of valence electrons that are free to move. Metals typically have high electrical conductivity because they have more free electrons.

Here are the types of elements represented by each of the options:

A. Ca (Calcium) - Alkaline Earth Metal B. Si (Silicon) - Metalloid C. Se (Selenium) - Nonmetal D. I (Iodine) - Nonmetal

Among these, Calcium (Ca) is a metal, and metals generally have higher electrical conductivity than nonmetals and metalloids. Therefore, Calcium (Ca) is most likely to have the highest electrical conductivity.
