The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)
Francium and lithium have the same number of valence electrons.
Francium has 87 protons and 87 electrons.
The ion Fr+ has 86 electrons.
Californium has 98 electrons and 98 protons; the number of neutrons is different for each isotope of Cf.
Francium has only one valence electrons.
