Astatine has 85 protons what is the atomic number?
The atomic number is the number of protons, so the atomic number of astatine is 85.
How many neutrons does Astatine 210?
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.
