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.
