__ is a _ElementDescription_. Its symbol is __ and its atomic number is __.
__ is a synthetic element in the periodic table that has the symbol __ and atomic number __.
Naturally occurring _ is composed of _ stable isotopes, _-_, _-_, and _-_, with _-_ being the most abundant (_% natural abundance). [1] Out of these, _ are of use in NMR and EPR spectroscopy. [2] _ radioisotopes have been characterized, with the most {abundant and/or stable} being _-_ with a half-life of _, _-_ with a half-life of _, and _-_ with a half-life of _. [1] All of the remaining radioactive isotopes have half-lives that are less than _, and the majority of these have half lives that are less than _. [1] This element also has _ nuclear isomers, with the longest-lived being _m-_ (t½ _), _m-_ (t½ _) and _m-_ (t½ _). [1] The nuclei of nuclear isomers exist in a delicate equilibrium or metastability due to at least one nucleon having an excited energy state.
The isotopes of _ range in mass number from _ to _ . [1] The most common decay mode(s) of _ isotopes with mass numbers lower than the most abundant stable isotope, _-_, is/are [[{name of decay mode}]] /and [[{name of decay mode}]], primarily forming _ isotopes (_ protons) /and _ isotopes (_ protons) as decay products.

Any changes to the infobox data should be checked against these pages, and/or the available references should be expanded accordingly, so that the decision for or against certain values remains transparent and easily retraceable.

Nonmetals are subdevided in diatomic nonmetals, polyatomic nonmetals (and noble gases, unchanged). The category other/poor metals is renamed into post-transition metals without further changes. This is the new scheme:
