Answer :
Answer:
In this case, an atom with 87 protons and an atomic mass of 197 has 110 neutrons.
Explanation:
To calculate the number of neutrons in an atom, you can use the following formula:
Number of Neutrons = Atomic Mass - Number of Protons
Given:
- Number of protons (atomic number) = 87
- Atomic mass = 197
Using the formula, you can find the number of neutrons:
Number of Neutrons = 197 - 87
Number of Neutrons = 110
Therefore, an atom with 87 protons and an atomic mass of 197 has 110 neutrons.
