{{Kotak info isotop kopernisium}}
'''[[Kopernisium]]''' ('''<sub>112</sub>Cn''') adalah  sebuah [[Unsur kimia sintetis|unsur buatan]], sehingga [[berat atom standar]]nya tidak dapat diberikan. Seperti semua unsur buatan, ia tidak memiliki satu pun [[isotop stabil]]. [[Isotop]] pertama kopernisium yang disintesis adalah <sup>277</sup>Cn pada tahun 1996. Ada 6 [[Radionuklida|radioisotop]] yang diketahui (dengan satu lagi yang belum dikonfirmasi); isotop yang berumur paling panjang adalah <sup>285</sup>Cn dengan [[waktu paruh]] 29 detik.
