Detailed explanation-1: -Oxygen-16 and oxygen-18 differ in the number of neutrons in their nuclei. Oxygen-16 has 8 neutrons, while oxygen-18 has 10 neutrons.
Detailed explanation-2: -Oxygen has three major isotopes: oxygen 16, oxygen 17, and oxygen 18. All of these isotopes have eight protons, but oxygen 16 also has eight neutrons. Oxygen 17 has nine neutrons, and oxygen 18 has 10 neutrons.
Detailed explanation-3: -Answer and Explanation: There are 10 neutrons in the nucleus of a single oxygen-18 atom.
Detailed explanation-4: -Since it is lighter than 18O, 16O evaporates first, so in warm, tropical areas, the ocean is high in 18O. Additionally, as water vapor condenses to form rain, water droplets rich in 18O precipitate first because it is heavier than 16O.
Detailed explanation-5: -Oxygen-16 and Oxygen-18 are two isotopes of Oxygen. Both have the same atomic number of 8. In other words, they have the same number of protons and electrons which is equal to 8.
