Answer :
Final answer:
The number of neutrons and electrons for a neutral isotope of iridium (Ir) with a mass number of 191 is 77 neutrons and 114 electrons.
Explanation:
The number of neutrons and electrons for a neutral isotope of iridium (Ir) with a mass number of 191 can be determined using the information provided.
The atomic number of iridium is 77, which is equal to the number of protons in the nucleus of an iridium atom. Since the isotope is neutral, the number of electrons is also equal to 77.
To find the number of neutrons, subtract the atomic number from the mass number: 191 - 77 = 114. Therefore, the correct answer is A) 77 neutrons and 114 electrons.
