 Oxygen-16

Oxygen-16 is the stable oxygen isotope with eight protons and eight neutrons. It is the most abundant oxygen isotope in ordinary terrestrial material.

Its nucleus has spin zero, unlike oxygen-17, so isotope choice changes which nuclear-magnetic-resonance experiments are possible. Isotopic identity therefore affects both mass-sensitive measurements and nuclear-spin observability without changing the element's proton number.

Oxygen-16, often represented as \(^{16}\text{O}\), is a stable isotope of oxygen. It is the most abundant isotope of oxygen, comprising about 99.76% of all naturally occurring oxygen. ### Key Characteristics of Oxygen-16: - **Atomic Number**: 8 (which means it has 8 protons in its nucleus).
