↑  mNo –  Isomer nuklir tereksitasi.
↑  ( ) –  Ketidakpastian (1σ) diberikan dalam bentuk ringkas dalam tanda kurung setelah digit terakhir yang sesuai.
↑  # –  Massa atom bertanda #: nilai dan ketidakpastian yang diperoleh bukan dari data eksperimen murni, tetapi setidaknya sebagian dari tren dari Permukaan Massa (trends from the Mass Surface, TMS).
↑  
Mode peluruhan:


EC:Penangkapan elektron

IT:Transisi isomerik

SF:Fisi spontan
↑  ( ) nilai spin –  Menunjukkan spin dengan argumen penempatan yang lemah.
1 2  # –  Nilai yang ditandai # tidak murni berasal dari data eksperimen, tetapi setidaknya sebagian dari tren nuklida tetangga (trends of neighboring nuclides, TNN).
↑  Tidak disintesis secara langsung, terjadi sebagai produk peluruhan dari 257Rf
