I can write and use the standard nuclear notation for different elements and their isotopes, and calculate relative atomic mass using isotope masses and abundancies.
Muuji qoraalka
Atoms of many elements vary in the exact number of neutrons in their nucleus, and each version is called an isotope.
Existence of isotopes results in relative atomic masses of some elements not being whole numbers.
Standard nuclear notation shows the chemical symbol, the mass number and the atomic number of the isotope.
The relative atomic mass is an average value that takes account of the abundance of the isotopes of the element.
