Notes

  1. ↑ 1.0 1.1 This element has no stable isotopes and no characteristic terrestrial abundance: no standard atomic weight can be given.
  2. ↑ Many of the properties of actinium are only known through estimation and/or extrapolation. Several estimates of the melting point and thermodynamic properties have been made; the boiling point was estimated on the basis of vapour pressure measurements. The density was determined by X-ray crystallography.
  3. ↑ The boiling point and thermodynamic properties of americium are calculated values.
