Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
The isotope with 86 protons and 136 neutrons is radium-222.
The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - 86 The isotope 222Rn, the most stable (half life = 3,8 days) radon isotope, has 136 neutrons.
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
The chemical element, Radon, has an atomic number of 86, meaning it has 86 protons. Were there an isotope of Radon that had 136 neutrons, it would be labeled as 222Rn. Well, it turns out that this isotope does exist and has a half-life of 3.82 days.

The isotope with 86 protons and 136 neutrons is radium-222.
The isotope 210Rn has 86 protons and electrons; also 124 neutrons.
Radon has 86 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a radon isotope = Mass number - 86
The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - 86 The isotope 222Rn, the most stable (half life = 3,8 days) radon isotope, has 136 neutrons.
The atomic number is 86 which gives the number of protons. 220Rn has 220 protons and neutrons so the neutron count iscalcualted as follows: 220 -86 = 134 neutrons 220Rn is an unstable isotope of Radon.
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
The element with 82 protons is lead (Pb). The number of electrons in a neutral atom of lead is equal to the number of protons, which is 82. To find the number of neutrons, you subtract the number of protons from the mass number, which is 125 neutrons for this isotope of lead.

There are 88 protons/electrons in radium. There are 138 neutrons.
Radon atomic number is 86 so it has 86 protons,86 electrons, and 136 neutrons. This is wrong!
The ratio of neutrons to protons in a nucleus of radon-222 can be calculated by subtracting the atomic number from the mass number. For radon-222, the atomic number is 86 and the mass number is 222. Therefore, the ratio of neutrons to protons in radon-222 is 222 - 86 = 136 neutrons to 86 protons.
