↑  mAr –  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

n:Emisi neutron

p:Emisi proton
↑  Simbol tebal sebagai anak –  Produk anak stabil.
↑  ( ) nilai spin –  Menunjukkan spin dengan argumen penempatan yang lemah.
↑  # –  Nilai yang ditandai # tidak murni berasal dari data eksperimen, tetapi setidaknya sebagian dari tren nuklida tetangga (trends of neighboring nuclides, TNN).
↑  Diyakini mengalami penangkapan elektron ganda menjadi  36S. Ia adalah nuklida tidak stabil secara teoritis paling ringan yang tak memiliki bukti radioaktivitas yang teramati)
↑  Digunakan dalam penanggalan argon–argon
↑  Nuklida kosmogenik
↑  Digunakan dalam penanggalan argon–argon dan penanggalan kalium–argon
↑  Dihasilkan dari 40K di bebatuan. Rasio ini terestrial. Kelimpahan kosmik jauh lebih kecil daripada 36Ar.
