Calculate the relative atomic mass of Neon given the isotopic masses and abundances.

The element is Neon (Ne) with three isotopes:

• $^{20}\text{Ne}$ has an isotopic mass of 20 amu and an abundance of $90.92\%$.
• $^{21}\text{Ne}$ has an isotopic mass of 21 amu and an abundance of $0.26\%$.
• $^{22}\text{Ne}$ has an isotopic mass of 22 amu and an abundance of $8.82\%$.

• For $^{20}\text{Ne}$: $\frac{90.92}{100} = 0.9092$
• For $^{21}\text{Ne}$: $\frac{0.26}{100} = 0.0026$
• For $^{22}\text{Ne}$: $\frac{8.82}{100} = 0.0882$

Relative Atomic Mass = $\sum (\text{isotopic mass} \times \text{fractional abundance})$

The relative atomic mass of Neon is $20.179 \text{ amu}$.
