86
To type the chemical symbol for Radon with its mass and atomic number on a computer, you can use the following format: ^222Rn. This notation indicates that Radon has an atomic number of 86 and a mass number of 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.
Since an alpha particle is a helium-4 nucleus, the resulting atom has an atomic mass that is 4 less, so 226 minus 4. Also, to get the element, look up the element number for radium, and subtract two from that.
The atomic number of fluorine is 9.The atomic number of sodium is 11.
Atomic number= number of protons. Hydrogen atomic number=1

226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
this elemnt has an atomic number that is double the atomic number of silicon?
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
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.
Subtract the atomic number from the atomic weight.
