Atomic Mass of First 30 Elements

 

What is the Atomic Mass of Elements?

The atomic mass of an element can be described as

the total mass of one atom of the given element. Its unit is called the unified atomic mass unit and is denoted by the symbol ‘u’.

Standard atomic weight is used to give the value of the mean of the atomic masses in a mixture of isotopes in a given sample of an element.
