Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers.
Number of neutrons = Atomic Mass of the isotope - 87
Francium has 87 positively charged protons and 87 negatively charged electrons, plus a varying number of uncharged neutrons, of which 136 is the commonest amount. Number of neutrons = Atomic mass of the isotope - 87
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.)
