Some facts#

ⓘ Remember: Isotopes are varieties of the same chemical element differing by mass number.
The atoms of two different isotopes have different numbers of neutrons in the atomic nucleus.
The number of protons (atomic number) for two different isotopes is identical. For this reason, it is still the same chemical element.
Isotopes can be divided into two groups due to their stability: stable and unstable (otherwise known as radioactive).
The percentage composition of stable isotopes is constant and specific for a given element.
ⓘ Example: There are three isotopes of oxygen in nature in the following percentages:
- ¹⁶O - 99.762%,
- ¹⁷O - 0.038%,
- ¹⁸O - 0.2%
The existence of isotopes is the main reason why the average atomic mass of elements is not an integer number.
