Why does Silver (Ag) have 1 electron in its 5th energy level?

Is there any real reason to why Silver has one electron in its 5th energy level? Woudn't it make sense for it to have 2?
Edit:
Shoudn't its electron configuration be [Kr] 5s
2
4d
9

The is a common trend Cr, Mo, Zn, Cu, Ag, Au all do it.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3.

There is a special stability associated with having a half-full or completely-full d shell. Since the 5s and 4d orbitals are so close in energy the added stability of a full d shell makes up for the cost of putting the electron in a 4d orbital instead of the 5s orbital (which is usually lower in energy than the 4d orbitals).
