Which of the following shows three elements in order of decreasing conductivity?

a. zn, pd, ag
b. pd, ag, zn
c. ag, pd, zn
d. zn, ag, pd

which of the following is the name of a metal?
a. k
b. potassium chloride
c. potassium
d. kci

C. Ag, Pd, Zn

C. Pottasium

Explanation:

It is a known fact that silver (Ag) is one most conducting metals so clearly Ag is most conducting than Zn (Zinc) and Pd (Palladium). so answer is C

in the second question

A. K is the symbol off Metal potassium in the periodic table

B. Potassium chloride is a Metallic salt not a metal

C. Potassium is a name of metal

D. KCl is The symbol of potassium chloride

so C is the answer

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

answer; natural resources;
