How many electrons are in francium?
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.)
How many protons and neutrons in francium?
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
Element francium has how many protons and neutrons?
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
How many protons neutrons and electrons are in Francium?
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
How much francium is there?
Francium is so rare its unable to be bought
