Web2 jun. 2024 · Each atom has an integer number of neutrons, but the periodic table gives a decimal value because it is a weighted average of the number of neutrons in the isotopes of each element. So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations. We know that the atomic number of radon is 86 and the atomic average mass number is about 222. Neutron = 222 – 86 = 136. Therefore, a radon atom has one hundred thirty-six neutrons.

Ukraine has found ways to make that much harder, in part by severing its connection to the Russian power grid and connecting to the European system. Russian forces tried repeatedly to hit the lines from Europe to Ukraine, and two major attacks in November did briefly sever that connection.
Radon-222 is generated in the uranium series from the alpha decay of radium-226, which has a half-life of 1600 years. Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. Its final decay product is stable lead-206. In theory, Rn is capable of double beta decay to Ra, and depending on the ma…
