Z is Atomic number. Sym is Atomic symbol. Name is the name of the element. Grp is the Group. Prd is the Period. Weight is the Atomic weight in Atomic mass units, with measurement uncertainty in parentheses (see Uncertainty#Measurements). Density is in grams per cubic centimeter. Melt is melting point in Kelvin. Boil is boiling point in Kelvin. Heat is specific heat capacity in Joules per gram-Kelvin. Neg is Electronegativity. Abund is Abundance of elements in Earth's crust in ppm by weight.

- ^1 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 standard atomic weights are given.
- ^2 The isotopic composition of this element varies in some geological specimens, and the variation may exceed the uncertainty stated in the table.
- ^3 The isotopic composition of the element can vary in commercial materials, which can cause the atomic weight to deviate significantly from the given value.
- ^4 The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given.
- ^5 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.
- ^6 Does not solidify at 1 atm, even near absolute zero, but does at 2.5 MPa at 0.95K.
- ^7 Sublimes at 1 atm
- ^8 Transuranic elements 95 and above do not occur naturally, but can be produced artificially.
