This produced one atom of moscovium-287 and three atoms of moscovium-288. All four atoms quickly decayed into other elements. Moscovium's most stable isotope, moscovium-289, has a half-life of about 220 milliseconds. It decays into nihonium-285 through alpha decay.
The periodic table of chemical elements is one of the most recognized tools in science. As we mark the 150th anniversary of the periodic table, the scientific community has declared 2019 to be “ The International Year of the Periodic Table ”.
GHS, the Globally Harmonized System of Classification and Labeling of Chemicals, was developed by the United Nations as a way to bring into agreement the chemical regulations and standards of different countries. GHS includes criteria for the classification of health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals ...
