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

A. Zn, Ag, Pd,

B. Pd, Ag, Zn

C. Ag, Pd, Zn,

D. Zn, Pd, Ag

The decreasing order of the electrical conductivity between elements Zn, AG and Pd is the following order:

Ag (silver), Zn (Zinc), Pd (Lead)

The correct option is not mentioned here.

Explanation: Conductivity of an element means property to pass energy in this material. Some elements have high conductivity than other elements. There are different types of conductivity like electrical conductivity, thermal conductivity etc. Silver has highest conductivity in elements. After that in given list zinc is highly conductive and lead is at third position.

Answer: Ag, Zn, Pd. (Ag is has the highest conductivity and Pd has the lowest conductivity).

Explanation:

The correct answer is not among the options given.

You must look up the electrical conductivity of these metals in a table of metal properties.

The values that you can find are:

Ag: 62.1 * 10⁶ Siemmens / m Zn: 16.6 * 10⁶ Siemmens / m Pd: 9.5 * 10⁶ Siemmens / m

So in order of decreasing conductivity the list is Ag > Zn > Pd.
