If an element has one and only one stable isotope, an example is Gold.
eeffefretr
For example a thorium isotope is Th-231 or 23190 Th.
An example with a zinc isotope: 81Zn (mass number as superscript before the chemical symbol)
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
Sodium chloride is a compound, not an isotope.
63Cu
If an element has one and only one stable isotope, an example is Gold.
Deuterium is an example of natural, non-radioactive isotope; deuterium is the isotope of hydrogen with 1 proton and 1 neutron.
eeffefretr
For example a thorium isotope is Th-231 or 23190 Th.
An example with a zinc isotope: 81Zn (mass number as superscript before the chemical symbol)
Tc99m
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
The chemical symbol of uranium is U.
hydrogen-1hydrogen-2carbon-12etc.
Ionized hydrogen-1 isotope is identical to a proton.
