Astatine-210 (At-210) has a mass number of 210. Since Astatine has an atomic number of 85, which indicates the number of protons, you can calculate the number of neutrons by subtracting the atomic number from the mass number: 210 - 85 = 125. Therefore, Astatine-210 has 125 neutrons.

How many isotopes does the element astatine from the periodic table have?
Astatine, a radioactive element found in the halogen group, has at least 20 known isotopes. However, only one of these isotopes, Astatine-210, is considered stable. The other isotopes are unstable and undergo radioactive decay.
If an atoms mass number is 210 and its atomic number is 85. how many nuetrons does it have?
To find the number of neutrons in an atom, you subtract the atomic number from the mass number. In this case, the mass number is 210 and the atomic number is 85. Therefore, the number of neutrons is 210 - 85 = 125. Thus, the atom has 125 neutrons.

What If there are 128 neutrons in Pb 210 how many neutrons are found in the nucleus of Pb 206?
Lead-210 has 82 protons, so 128 - 82 = 46 neutrons in Pb-210. Lead-206 has 82 protons, so since it's a different isotope, the number of neutrons will differ. Lead-206 has 206 - 82 = 124 neutrons.
