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 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 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
Neutrons - 118 Protons/electrons - 79
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
Manganese has 25 protons, 25 electrons and 30 neutrons.
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 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
Neon has 10 protons and 9 neutrons.
Neutrons - 118 Protons/electrons - 79
There are 87 electrons is Francium. There are also 87 protons, 87 neutrons and, by extension, the atomic number is also 87.
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
Oxygen is a p block element. It has 8 protons and neutrons.
Each element has a different number of protons and neutrons. So it changes for each element.
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
Boron has 5 neutrons and 5 protons for its most common isotope
