Boron has two isotopes - BYJU'S
Step1. Formula for average atomic weight. Average atomic weight = f 1 M 1 + f 2 M 2 + … + f n M n. Here f is the fraction representing the natural abundance of the isotope and M is the atomic mass of the isotope. Step2. Calculation of average atomic weight. Average atomic weight = 0. 20 × 10 g + 0. 8 × 11 g = 2 + 8. 8 g = 10. 8 g. Hence ...

First 20 Elements with Symbols and Atomic Number (Table) - BYJU'S
The total mass of one atom of a specific element is defined as the atomic mass of that element. Its unit is termed the unified atomic mass unit and is signified by the symbol ‘u’. Standard atomic weight is utilised to deliver the value of the mean of the atomic masses in a mixture of isotopes in a provided sample of an element.
