Among ¹⁴⁰₅₅Cs and ¹³³₅₅Cs, <u>¹³³₅₅Cs</u> is more stable.
<h3>Briefly explained</h3>
Let's review the criteria that are used to determine a stable isotope. A stable isotope will have more neutrons than protons with a neutron to proton ratio somewhere between one and 1.52 On the high atomic number, we're up to 152 at low atomic numbers were closer to one. More stable isotopes have an even number of protons. And neutrons.
And stable isotopes have their proton or neutron number equal to one of these magic numbers. So if we have season one, It has 85 Protons are start 85 neutrons And 55 protons. So we have a neutron to proton ratio of 155 for CCM 1 33. We have 78 neutrons and 55 protons for a neutron to proton ratio of 1.42. 155 is a little high for z equal to 55.
Both of these are also odd. So ¹⁴⁰₅₅Cs is the least stable. ¹³³₅₅Cs is the most stable.

They make science a thing. Science isn't just space and microbes etc. We need science to solve things in society, politics, and economics.
Answer: why do I think that water boils when the vapor pressure is equal to the atmospheric pressure?
because The pressure level of a liquid lowers the number of pressure exerted on the liquid by the atmosphere. ... pressure level may be increased by heating a liquid and causing more molecules to enter the atmosphere. At the purpose where the pressure level is up to the air pressure boiling will begin.
