सन्दर्भ
- ↑ अ आ इ ई उ ऊ ए ऐ ओ औ क ख ग घ ङ च छ ज झ ञ ट ठ ड ढ ण त थ द ध न प फ ब भ म य र The element does not have any stable nuclides, and a value in brackets, e.g. [209], indicates the mass number of the longest-lived isotope of the element. However, three elements, thorium, protactinium, and uranium, have a characteristic terrestrial isotopic composition, and thus their atomic mass given.
- ↑ अ आ इ ई उ ऊ ए ऐ ओ औ क ख ग घ ङ च छ ज झ ञ ट ठ ड ढ ण त थ द ध न प फ ब भ म य र ल व The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
- ↑ अ आ इ ई उ ऊ ए ऐ ओ औ क ख ग घ ङ The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
- ↑ अ आ इ ई उ ऊ ए ऐ The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
- ↑ The atomic weight of commercial Lithium can vary between 6.939 and 6.996—analysis of the specific material is necessary to find a more accurate value.
