zero

Explanation:

#Fr^+# is the ionized form of the element. The definition of the valence level is 'the highest principle quantum number of the electronic configuration'.

#Fr^o[Rn]7s^1# + 1st Ionization Energy => #Fr[Rn]^+ + 1e^-#

Since the #7s^1# electron is no longer present in #Fr[Rn]^+# and n = 7 is the highest principle quantum number then there are no electrons in the valence level.
