Final answer:
The isotope ¹⁶₈O has 8 protons and 8 neutrons, corresponding to option A. The isotope ¹⁶₈O belongs to the element oxygen, which has an atomic number of 8. The number ¹⁶ represents the mass number, which is the total number of protons and neutrons in the nucleus of the atom. Therefore, the isotope ¹⁶₈O has 8 protons and 8 neutrons.
Step-by-step explanation:
The isotope ¹⁶₈O represents an oxygen isotope with an atomic number of 8 and a mass number of 16. The atomic number tells us the number of protons, which is 8 for oxygen. The mass number is the sum of the protons and neutrons, so to find the number of neutrons, we subtract the number of protons from the mass number: 16 - 8 = 8 neutrons. Therefore, the isotope ¹⁶₈O has 8 protons and 8 neutrons, making option A (Protons: 8, Neutrons: 8) the correct answer.
The isotope ¹⁶₈O has 8 protons and 8 neutrons.
An isotope is a form of an element that has the same number of protons but a different number of neutrons. The isotope ¹⁶₈O belongs to the element oxygen, which has an atomic number of 8. The number ¹⁶ represents the mass number, which is the total number of protons and neutrons in the nucleus of the atom. Therefore, the isotope ¹⁶₈O has 8 protons and 8 neutrons.
