Question

which one is most reactive element. silver lead copper zinc​

Answer 1

"Among the all the options given in the question,

Zinc is the most reactive element, compared to silver, lead and copper. Zinc reacts with dilute acid compared to the other elements which barely reacts with acids or water. Zinc lies above silver, lead and copper in the activity series, so zinc is more reactive as compared to the other elements mentioned in the question.  

"

Answer 2

Zinc is more reactive than the copper, lead and silver.

Explanation:

• The outermost electrons that are in the "4s orbital" for both the copper and zinc, but the Zn has two more electrons in the 4s, when the Cu has only one.
• So, the zinc is formed a 2+ ion easily in the solution and the copper can't be displace Zn in the solution because for losing the two electrons that it would be a necessary thing to break up the closed 3d sub-shell.
• So, the zinc is more reactive than the other metals.

To know more:

Study the following chemical reactions,the most reactive element is

Cu+2Ag(No3)2---->Cu (NO3)2+2Ag

Pb+Cu(No3)2------>PB(No3)2+Cu

Zn+PB(NO3)2----->Zn(No3)2+PB

A. AG (silver)

B. Pb ( lead)

C. Cu(copper)

D.Zn(zinc)
