Francium has 87 protons.
It is not true: francium has 87 protons.
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
Francium has 87 protons; the number of neutrons is different for each isotope and francium has approx. 40 isotopes and isomers. Number of neutrons = Atomic mass of the isotope - 87
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
Californium has 98 electrons and 98 protons; the number of neutrons is different for each isotope of Cf.
Chromium has 24 protons and francium has 87 protons.
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 protons and 87 electrons.
There are 87 electrons is Francium. There are also 87 protons, 87 neutrons and, by extension, the atomic number is also 87.
Francium 2x + 60 = 234 x = 87 protons. So you have to have 147 neutrons. Francium has 87 protons, and the neutrons come from the isotope.
Cobalt has 27 protons and francium has 87 protons; 87-27=60.
As all chemical elements francium contain protons, neutrons and electrons.
