To find the number of neutrons in an atom, you can use the formula:
\[
\text{Number of neutrons} = \text{Mass number} - \text{Atomic number}
\]
In this case, the mass number is 210 and the atomic number is 85.
So, substituting the values:
\[
\text{Number of neutrons} = 210 - 85 = 125
\]
Therefore, the atom has 125 neutrons.
\[
\text{Number of neutrons} = \text{Mass number} - \text{Atomic number}
\]
In this case, the mass number is 210 and the atomic number is 85.
So, substituting the values:
\[
\text{Number of neutrons} = 210 - 85 = 125
\]
Therefore, the atom has 125 neutrons.
