Notas

1 L'elemento no tien isotopo estable, y una valura entre parentesis, per eixemplo [209], indica la masa atomica d'o isotopo con vida meya mes gran de l'elemento u composición isotopica caracteristica.

2 A composición isotopica d'iste elemento vareya en belas muestras cheolochicas, y a variación puede sobreixer a incerteza sinyalata en a tabla.

3 A composición isotopica de l'elemento puede variar en materials comercials, o que puede causar que o peso atomico seiga bien diferent a la valura data.

4 A composición isotopica vareya tanto en materials terrestres que no se puede dar una valura mes precisa d'o peso atomico.

5 Lo peso atomico d'o litio comercial puede variar entre 6.939 y 6.996. Ye menister una analís d'o material especifico ta trobar una valura mes exacta.
