Moving freely between the cations
Answer: 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.

N(Ca)=3×N(Ca₃(PO₄)₂)=
=3×2.3×10²³=6.9×10²³
6.02×10²³→40g
6.9×10²³→Xg
m(Ca)=X≈45.85g
