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.
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
Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
Nuclear fission of some isotopes release a great quantity of energy. Plutonium is a fissile material (isotopes 239Pu and 241Pu); it is used in nuclear reactors and nuclear weapons. Also Pu(alpha,n)Be is a source of neutrons and Pu is used as power or heat source.
In the case of Rn-222, which is the "isotope of concern" because it occurs naturally, it decays as follows: 222Rn => 218Po + He+2 In this equation, we see the radon isotope Rn-222 emit an alpha particle (the helium nucleus) and undergo a transformation to become the polonium isotope, Po-218.
The isotope 210Rn has 86 protons and electrons; also 124 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.
See an example at: http://education.jlab.org/qa/atom_model.html and note that thorium 232 has 90 protons, 142 neutrons and also 90 electrons; the electron configuration is [Rn] 6d27s2.
Radon Rn
The element that has 86 protons in period 6 is Radon (Rn).
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
Radon has 86 protons in it's nucleus.
The number of protons is the same as the elements Atomic Number (86). So you can look it up on the Periodic Table.Element 86 is the gas Radon.NOTE is it NOT in period 4 it is in period 6
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.
An alpha particle consists of 2 Neutrons and 2 Protons, therefore A=4, Z=2.For Ra-224: A=224, Z=88.Subtracting the values for the alpha particle from Radium-224:A = (224-4) = 220Z = (88-2) = 86The nucleus with a Z of 86 is Radon, or in this case, Rn-220.So that: Ra-224 --> Rn-220 + AlphaBut alpha particles are just Helium-4 nuclei.Ra-224 --> Rn-220 + He-4
