Explanation:
Below is an attachment containing the solution.
Answer:
d. 75 protons, 110 neutrons
Explanation:
In an isotope, the number next to the number of the atom is the mass number (Protons + neutrons). Rhenium has as atomic number 75, that means Rhenium has <em>75 protons</em>. As atomic mass, 185, is the sum of protons and neutrons, number of neutrons is:
185 - 75 = <em>110 neutrons</em>
<em />
Thus, right answer is:
<em>d. 75 protons, 110 neutrons
</em>

I believe it is stable and it is a nobel gas (group 18)
Protons and neutrons are located at the nucleus.
Electrons are located on the outer shells, or orbitals.
Subatomic Particles are located inside of the atoms. Protons, neutrons, and electrons.
