An actinoid or actinide[Note 1] is an element with an atomic number between 89 and 103, that is, one of Ac, Th, Pa, U, Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No or Lr.[1] The idea of a series of fourteen elements analogous to the lanthanoids was proposed by Glenn Seaborg in 1946.[2]

Notes

  1. IUPAC prefers the term "actinoid", as "actinide" refers to a binary compound of actinium with a more electropositive metal.[1]
