Answer:

#Ag^+ rarr Ag^0darr#

Explanation:

Silver ion undergoes a change in oxidation state from #+I# to #0#. Since silver has undergo a DOWNWARD change in oxidation state, it has been formally reduced.

On the other hand, elemental sodium has gone from #Na^0# to #Na^+#; that is, it has been OXIDIZED.
