Studies of the heaviest nuclei and heaviest chemical elements are shortly described. Methods of synthesis and identification of these nuclei are discussed. Some details of the studies are illustrated on the example of the nucleus 277Cn, the isotope of the element 112 (copernicium) the discovery of which has been recently approved by IUPAC. General results of the research on superheavy nuclei (atomic number Z = 104–118), synthesized within the period from 1969 (discovery of rutherfordium, Z = 104) up to the present are outlined.
