Answer :
Final answer:
The atom with 83 electrons, 87 protons, and an atomic mass of 197 has 110 neutrons, calculated by subtracting the number of protons from the atomic mass.
Explanation:
To calculate the number of neutrons in an atom, you can use the formula:
number of neutrons = atomic mass - number of protons.
Given that the atom has 83 electrons, 87 protons, and an atomic mass of 197, we can calculate the number of neutrons as follows:
Number of neutrons = Atomic mass - Number of protons
Number of neutrons = 197 - 87
Number of neutrons = 110
Therefore, the atom has 110 neutrons.
