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

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.

Answer:

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.
