टीका टिप्पणी
 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, four such elements, bismuth, thorium, protactinium, and uranium, have characteristic terrestrial isotopic compositions, and thus their standard atomic weights are given.
 The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
 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 isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
 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.
 This element does not solidify at a pressure of one atmosphere. The value listed above, 0.95 K, is the temperature at which helium does solidify at a pressure of 25 atmospheres.
 This element sublimes at one atmosphere of pressure
 The transuranic elements 95 and above do not occur naturally, but some of them can be produced artificially.
 The value listed is the conventional atomic-weight value suitable for trade and commerce. The actual value may differ depending on the isotopic composition of the sample. Since 2009, IUPAC provides the standard atomic-weight values for these elements using the interval notation. The corresponding standard atomic weights are:
Hydrogen: [1.00784, 1.00811]
Lithium: [6.938, 6.997]
Boron: [10.806, 10.821]
Carbon: [12.0096, 12.0116]
Nitrogen: [14.00643, 14.00728]
Oxygen: [15.99903, 15.99977]
Magnesium: [24.304, 24.307]
Silicon: [28.084, 28.086]
Sulfur: [32.059, 32.076]
Chlorine: [35.446, 35.457]
Bromine: [79.901, 79.907]
Thallium: [204.382, 204.385]
 Electronegativity on the Pauling scale. Standard symbol: χ
 The value has not been precisely measured, usually because of the element's short half-life; the value given in parentheses is a prediction.
 With error bars: 357 K.
 This predicted value is for liquid ununoctium, not gaseous ununoctium.
