What is the abundance of oxygen-16?
99.762%
Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.
How many isotopes does o 16 have?
three isotopes
Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. For example, there are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18.

What is isotopic abundance?
Isotopes have different atomic masses. The relative abundance of an isotope is the percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element.
How do you find the abundance of 3 isotopes?
Calculate the average atomic mass using the atomic masses of each isotope and their percent abundances. Divide each percent abundance by 100 to convert it to decimal form. Multiply this value by the isotope’s atomic mass. Add the atomic masses of each isotope together to get the average atomic mass.
What does high O18 mean?
cold climates
Oceanic delta-O-18 values that are high represent cold climates, while lower values indicate a warm climate. This trend occurs because of the effects of precipitation and evaporation. Since it is lighter than 18O, 16O evaporates first, so in warm, tropical areas, the ocean is high in 18O.
