The atomic number of radon is 86. This means there are 86 protons in it. In an atom, the number of protons and electrons are always equal so that their is no net charge on the atom (protons are positively charged and electrons are negatively charged).
Therefore the number of electrons in a radon atom is also 86.
The number of neutrons can be calculated by subtracting the atomic number from the atomic mass. Atomic mass is the sum of all the particles that comprise an atom. Since the mass of electrons is negligible, the atomic mass is equal to the sum of the number of protons and the number of neutrons.
The number of protons is 86 and the atomic mass is 222.
Thus, the number of neutrons is:
222-86
= 136
Hence, there are 136 neutrons in an atom of radon.

Summarizing the whole answer, we can say that in radon, the
No. Of protons is 86;
No. Of electrons is 86; and
No. Of neutrons is 136.

The previous work for your problem did not include the no. Of electrons, in my work I will provide the electron configuration as well.

Radon (elemental symbol Rn) has,

86 protons
and therefore to be electrically neutral 86 electrons
and 222-86=136 neutrons

and electron configuration: 1s2 2p2 3p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f14 5d10 6s2 6p6

The atomic number of an element is actually the number of protons in it. If you take a look at the Periodic Table, you will see that the atomic number of radon is 86. This means that the number of protons in radon is 86.

In all atoms, the number of protons is always equal to the number of electrons. Protons are positively charged atoms but an atom does not have any charge. Why so? Actually, the positive charge of an atom is neutralized by the negative charges in the atom. Electrons are these negatively charged particles. When the number of electrons is equal to the number of protons, the atom loses its charge. That is why, when atoms lose electrons, positive ions are formed (cations) as the number of protons (positive) increase and are more than the electron (negative). Thus, the net charge on the ion becomes positive. You can also describe the negative ions (anions) that atoms form by gaining electrons (negative particles). Long story short, the number of electrons in radon is also 86.

Finding out the number of neutrons is also not difficult. For this we need the atomic mass which we also find out from the periodic table. The atomic mass is the sum of the number of protons and the number of neutrons. We already know the number of protons from the atomic number, so we can easily find the number of neutrons by subtracting the atomic number from the atomic mass:

Atomic Mass= Number of protons + Number of neutrons

Number of neutrons = Atomic Mass - Number of protons
Number of neutrons = 222 - 86
  = 136

So, radon has:
86 protons
86 protons
136 neutrons

Radon is a radioactive element, the name is originated from the Latin word 'niten' which means shining. The atomic number of Radon is which means that it has 86 protons in the nucleus since the number of protons is equal to the number of electrons in the neutral state so the total number of electrons is also 86.The total number of neutrons in the nucleus is 136. The element is crystalline in nature and the shape of crystals is cubical (when cooled down and crystallized). It is a radioactive element which is produced by the disintegration of radium. It is a heavy inert gas located in the noble gas group of the periodic table (which is group number 18 of periodic table), as it is clear that in the periodic table all the elements are arranged in order of their atomic numbers so this element has a specific position accordingly.It does not readily react chemically unless specific conditions are met.

Although it is a very rarely used element however it is used in treatment of cancer and in the instruments for detecting earthquakes. In some research laboratories it is even used for producing neutrons. The density of Radon is 9.73 g/cm3. The boiling point of this radioactive element is -61.80C and the melting point is -71.00C.

Thank you, thank you, thank you. I was freaking out that i wouldn't be able to find the amount of protons in the nueclus of radon. You just saved me from failing my project. My parner would kill me if i couldn't find it. THANK YOU!!!!!!!!!! You rock.

The number of electrons and the number of protons in an ion of radon are the same. The electron configuration of an ion of radon comprises six shells of electrons.

The first shell of electrons in an ion of radon comprises two electrons. The second shell of electrons in an ion of radon comprises eight electrons. The third shell of electrons in an ion of radon comprises eighteen electrons. The fourth shell of electrons in an ion of radon comprises thirty-two electrons. The fifth shell of electrons in an ion of radon comprises eighteen electrons. The sixth (and final) shell of electrons in an ion of radon comprises eight electrons.

The numbers of protons in an ion of radon are also two, eight, eighteen, thirty-two, eighteen and eight in the six protons shells of radon.
