Estimate

A randomly chosen natural oxygen atom is oxygen-16

Probability:
99.757%
Odds:
411 to 1
dBan
+26.1 dBan

In a representative natural composition, oxygen-16 makes up about 99.757% of oxygen atoms.

Calculation

p ≈ 0.99757 for oxygen-16

Assumptions

The model uses a representative natural isotopic composition. Isotope fractions vary by material.
