  2. Moscovium - Wikipedia

    en.wikipedia.org/wiki/Moscovium

    Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds. [9] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen.

    This list of chemical elements named after places includes elements named both directly and indirectly for places. 41 of the 118 chemical elements have names associated with, or specifically named for, places around the world or among astronomical objects.

  4. Livermorium - Wikipedia

    en.wikipedia.org/wiki/Livermorium

    Moscovium and livermorium are expected to be volatile enough as pure elements for them to be chemically investigated in the near future, a property livermorium would then share with its lighter congener polonium, though the short half-lives of all presently known livermorium isotopes means that the element is still inaccessible to experimental ...

  5. Pnictogen - Wikipedia

    en.wikipedia.org/wiki/Pnictogen

    All pnictogens up to antimony have at least one stable isotope; bismuth has no stable isotopes, but has a primordial radioisotope with a half-life much longer than the age of the universe (209 Bi); and all known isotopes of moscovium are synthetic and highly radioactive.

    en.wikipedia.org/wiki/Californium

    Twenty isotopes of californium are known (mass number ranging from 237 to 256 [11]); the most stable are 251 Cf with half-life 898 years, 249 Cf with half-life 351 years, 250 Cf at 13.08 years, and 252 Cf at 2.645 years. [11] All other isotopes have half-life shorter than a year, and most of these have half-lives less than 20 minutes. [11]

  8. Isotopes of moscovium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_moscovium

    Moscovium (115 Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no known stable isotopes. The first isotope to be synthesized was 288 Mc in 2004. There are five known radioisotopes from 286 Mc to 290 Mc. The longest-lived isotope is 290 Mc with a half-life of 0.65 seconds.
