In a piece of silver, where would you find the valence electrons? (a) moving freely between the cations (b) attached to anion (c) attached the cation (d) shared between a cation and anion

Option (A) is the correct answer.

Explanation:

The valence electrons are the electrons which are present in the outermost shell of an atom.  

A silver atom contains a positive charge as silver is a cation.

In a piece of silver, the silver atoms will be linked together. As it is known that silver is a cation, it will hold a positive charge.

Therefore, it can be concluded that in a piece of silver, the valence electrons will be moving freely between the cations.
