    Light Nuclei
AI Thread Summary
The discussion centers on the differences in mass and stability between atomic nuclei. Heavier nuclei tend to be less stable, with a general trend that very heavy nuclei are all unstable. The mass of a nucleus is determined by the number of protons and neutrons it contains, with heavier nuclei having more of both. Light stable nuclei typically have a balanced ratio of protons to neutrons, while heavier stable nuclei exhibit a higher neutron-to-proton ratio.

What's the difference between them?
 
Chemistry news on Phys.org
Mass.

Perhaps if you will ask a little bit more elaborate question it will be possible to give a little bit more elaborate answer.

um which ones are more stable? How is one more massive than the other (Do heavy nuclei have more protons or nuetrons)?

No simple rule. In general heavier ones are less stable, but a lot depends on the number of protons and neutrons present. Very heavy ones are all unstable.

How is one more massive than the other (Do heavy nuclei have more protons or nuetrons)?

They have more of both. Light stable nuclei have about the same number of protons and neutrons, the heavier the stable nucleus, the higher the neutron/proton ratio.

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
