Caesium area stability trend data
[edit]After the occurrence of 9 stable isotopes in 54 Xe with the heaviest being EE54Xe136 and having 82 neutrons (28extra neutrons above the Z number), the element 55Cs is noted to be Monisotopic with only 1 stable isotope at OE55Cs133 with only 78 neutrons (23 extra neutrons above the Z number). It also is the beginning of a stability trend away from higher stable extra neutron isotopes for 4 more isotopes down to the also Monisotopic element OE59Pr141 with 82 neutrohns (and 23 extra neutrons above the Z number). This evidently results in a rebalancing of the structure of the atom such as to permit it to return to the accumulation of 2 neutrons per ptoton along a stability trend line with the formula A = 3Z - 36 (except for 61Pm), which runs from OE59Pr141 up to EE68Er168 (which has 100 neutrons and 32 extra neutrons above the Z number), a span of 10 elements. This structural stability decay after 54Xe and subsequent return after 59Pr is indicative that the stability of the atom is related to its structural features as well as to its electrostatic and magnetic properties.WFPM (talk) 10:35, 3 November 2010 (UTC)
Also note that in accordance with the indications of the Janet periodic table, see Charles Janet, the element 55Cs is involved with the accumulation of the first half (deuteron) half of the 6th alpha particle that is incorporated into the nucleus of the atom, which may explain the instability until the 6th alpha particle accumulation is completed in 56Ba, and that 56Ba has 7 stable isotopes up to EE56Ba138 with 82 neutrons (and 26 extra neutrons above the Z number) and 72 percent constituency.WFPM (talk) 10:35, 3 November 2010 (UTC)
It is finally noted that on the low side of the center of stability (OE55Cs133) The half-life values of the OO isotopes falls off drastically in comparison to the to the half-lives of the OE isotopes (by about 2 orders of magnitude). This occurs to the isotopes OO55Cs130, OO55Cs128, OO55Cs126, And OO55Cs124.WFPM (talk) 23:24, 21 April 2013 (UTC)
Grammar correction
[edit]" ... caesium isotopes were released into the atmosphere where it is absorbed readily into solution and is returned to the surface of the earth ... " There's a number inconsistency here: "isotopes" is the subject, and is obviously plural - but the following pronoun ("it") is obviously singular, as is the associated verb. Wouldn't " ... caesium isotopes were released into the atmosphere where they are readily absorbed into solution and are returned to the surface of the earth ... " be better? 121.44.172.159 (talk) 08:20, 16 December 2013 (UTC)Hawkeye
- I corrected the number by substituting caesium for it: "where caesium is absorbed." There may be a further problem in the article of not distinguishing Cesium for its ions. (PeacePeace (talk) 15:13, 21 September 2017 (UTC))

Does Article confuse Cesium ions with Cesium?
[edit]It is well known that the properties of elemental metals differ greatly from the properties of their ions. For example, sodium ions are part of salt, a staple of human life. But elemental sodium is corrosive, a poison. Thus I suggest that the article be revised to be accurate in this regard. For example, the article states:
- "caesium isotopes were released into the atmosphere where caesium is absorbed readily into solution and is returned to the surface of the earth . . . ."
- Is it cesium that was released or its ions? (PeacePeace (talk) 15:08, 21 September 2017 (UTC))

Most isotopes
[edit]This page currently says Caesium, Barium and Mercury have the most at 40 isotopes.
The page for Xenon cites 40... 34 known.
The page for Tin cites 41... only 39 known.
(I didn't realise: their pages have a # symbol for isotopes that are "derived").

Possible alpha decay of 139Cs and 140Cs
[edit]139Cs and 140Cs respectively have an alpha decay energy of 0.66 MeV and 0.03 MeV, which are quite low, so alpha decay may be possible but with a half-life long beyond imagination. 129.104.241.214 (talk) 23:33, 24 October 2023 (UTC)
