Calculate the number of neutrons for an atom with 83 electrons, 87 protons, and an atomic mass of 197.

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.
